Image is everything.

These three words have infamously followed Andre Agassi throughout his tennis career both on and off the court.

Andre Agassi wearing a wig at the Men's French Open finals on June 9, 1991 and four years later during a third-round match on June 2, 1995 in Paris.

Agassi admits in his shocking new autobiography, “Open,” that he once lied to tennis’ governing body about using the highly-addictive drug crystal-meth and got away with it.

Perhaps equally shocking, the revelation despite all of his success, he hated playing the sport his entire life. A sport that netted him not only fame and fortune but what he says emptiness and depression.

As one of the world’s most well-known and respected athletes and in a sport where he is considered one of the greatest of all-time, what does Agassi and his image stand to gain with these admissions?

Agassi has been a man of many images over the years. From his early playing days sporting a lion-mane hairstyle now known to be a wig, his glamorous Hollywood romantic relationships, to becoming one of the ultimate champions of his sport, Agassi’s book chronicles a life that he says he never chose and an image he couldn’t escape.

An opportunity to reconcile his past with both his fans and himself, Agassi says that he wants the world to know his true story. He wants others to pursue a life of their own making where image isn’t everything.

Andre Agassi will be our Connector of the Day this Thursday. Send him your questions

Amitabh Bachchan rose to fame in the early 1970s as one of the hot new faces of Bollywood and has since become one of the elder statesmen of Indian cinema, having won many major awards in his long career.

Amitabh Bachchan receives the Lifetime Achievement Award at the 11th Mumbai Film Festival in 2009.

As well as being an actor, Bachchan has also worked as singer, film producer and as a television presenter. He was also elected as a member of the Indian parliament from 1984 to 1987. His career has not been without controversy: two years amid local elections in Uttar Pradesh he made a film in support of the Mulayam Singh government but his own party lost heavily in the elections.

The fall of the Berlin Wall on November 9, 1989 heralded the fall of communism in Europe and ultimately the end of the Cold War between the West and the Soviet Union.

Graffiti is painted on Berlin Wall on West Berlin side while East German and Soviet flags fly on the other side of the East Berlin no-mans-land spiked with anti-tanks traps.

Overnight the world changed. Suddenly the people of eastern Europe were able to travel freely. Many of the former countries of the Soviet bloc eventually joined the European Union and Nato, something that would have been unimaginable before the Wall fell.

While all this has meant the threat of imminent nuclear war in Europe is over, many remain nostalgic for the strict certainties of the old regimes, when a job for life was common despite economic deprivation.  Reunification of Germany has also proved to be easier said than done while many point to resurgent nationalism in the former Soviet bloc as a worrying trend.

We want you to share your memories and to hear your comments. Tell us where you were when the Wall fell. Do you think the world is a better place now? How has it changed and have lessons been learned? We will try to use as many comments as possible on tonight's Connect the World show.

Dolly Parton introduced herself to the country music charts in 1967, at the age of 21, with her debut album "Hello, I'm Dolly."

Dolly Parton is as famous for her image as her many hits.

A successful partnership with Porter Wagoner, the host of the television show of the same name, put her on the national stage.

Forty albums have followed, including a succession of No. 1 hits, awards and high-profile performances on television and film.

She's almost as famous for her image as her vast array of hits. Striking sculptured hair, bright lashings of eye shadow caked on a face that she has admitted in the past owes a lot to modern surgery, and always very high heels.

In 1986, Parton's megastar status was confirmed with the opening of her own theme park "Dollywood." In 2001, a water park, "Dollywood's Splash Country," opened next door.

If you've got any comments on the country singer with four decades of performing behind her - and still going strong - have your say here.

German DJ legend Paul van Dyk  joins us to talk about the 20th anniversary of the fall of the Berlin Wall.

Send your questions for Paul Van Dyk.

He is considered to be one of the leading "trance" DJs in the world, with sold-out tours that cross each continent, headline spots at every major festival, and a hugely successful recording career.

The momentous events of that period had a huge impact on the young van Dyk, as he grew up in East Berlin before escaping to West Germany shortly before the fall of the Wall on November 9, 1989.

His love of dance music started when he listened to smuggled mixtapes as a teenager. By the early 1990s van Dyk was spinning regularly at various clubs in Berlin before he released his first album "45 RPM" in 1994. 

His second album "Seven Ways" catapulted him into the Top 100 and brought him to the attention of a wider audience outside Germany.

Aside from his musical activity, van Dyk  has an active interest in politics and social justice.  He has a children’s charity based in the Indian city of Mumbai, and a partnership scheme with the German Red Cross to help poor children in his native Berlin.

He has now penned a musical tribute called "We Are One," which he'll play at the 20th anniversary Festival of Freedom celebrations  at the German capital's Brandenburg Gate on Monday.

Tell us what we should ask Paul and we'll put the best questions to him during the show.

Landmark news events come in two forms. There are the 9/11s which we remember for all the wrong reasons and there are the Berlin Walls which we remember for happier reasons.

Tell us your memories of the fall of the Berlin Wall.

The Wall was the focal point of the Cold War which could have ended in disaster but didn't, instead it ended in a street party. The people who celebrated on November 9th 1989 on the rubble of the Wall still struggle to describe that night.

They knew they were witnesses to history but they couldn't fathom the extent of it. Those who weren't there but were watching it on TV from afar had the benefit of expert commentary and probably got their heads round it more quickly. Where were you? What were you thinking?

And what do you think of Berlin today? It's been transformed into a thoroughly modern capital worthy of its reputation as Europe's capital of cool. But has it lost its way and its identity? Former East Germans speak fondly of a devided Berlin with a simpler way of life and a greater sense of community.

Your thoughts on Berlin then and now are our talking points for this week's webcast. Send us comments.

If ever there was an example of where the international effort in Afganistan isn't working, it came this week.

British soldiers mentor Afghan police. But has the risk become too great?

Five British soldiers were killed by an Afghan policeman they had been training. It came as no surprise that the Taliban claimed to have infiltrated the police and carried out the attack, but it was still a major dent in confidence of British forces who believe they are making a difference.

Kim Howells, a former Foreign Office minister with responsibility for Afghanistan, said the killings strengthened the case for bringing British troops home early.

The current UK government responded by saying forces will only be withdrawn once the Afghans have been given the training and support they need to protect the country themselves.

But, given possible infiltration, should the training continue despite the risk to more foreign soldiers' lives?

When you consider the victims in a war crimes trial, you don't normally consider the defendant first.

How should the war crimes court handle Radovan Karadzic's trial?

But ex-Bosnian Serb leader Radovan Karadzic is trying to play that card in The Hague: he's trying to take control of the proceedings by portraying himself as a victim, denied justice by the West, and sinking under the weight of more than a million pieces of paperwork thrown at him by the prosecution.

I have heard western lawyers suggest that the best thing for everyone is for him to boycott the trial so the prosecution can make its case without further distraction.

But justice should be seen to be done and, vitally, all parties concerned - including Bosnian Muslims and Serbs – need to perceive the trial as fair. How does the court strike the right balance?

Muhammad Yunus received the Nobel Peace Prize in 2006 for his pioneering work in “microcredit” which has helped millions of people out of the poverty cycle.

Send your questions for Muhammad Yunus.

The first businessman ever to receive such a high honor, Yunus has revolutionized conventional ways of banking, creating a system of lending small amounts to entrepreneurs with no collateral.

Recently he has backed the Nobel committee's controversial decision to award the 2009 peace prize to U.S. President Barack Obama.

Yunus set up the Grameen bank in Bangladesh in 1983 (Grameen literally means "of the village" in Bengali), and has since disbursed about $8 billion to Bangladeshi micro-entrepreneurs, 97 percent of whom are women in businesses such as street vending and farming.

The bank's concept is simple. “Credit is a basic human right”, says Yunus. “Offer even a small credit and a person will work out how to best use it to break free of poverty”.

The average loan is just $220, and repayments are near 100 percent. This "microcredit" model has been copied all over the developing world.

In 2009 during a global economic recession Grameen has been little affected according to Yunus. In fact it has now set its sights on helping the poverty-stricken in the U.S.

After the subprime mortgage meltdown and tougher standards by lenders, poor Americans deemed unworthy of credit by commercial banks now have somewhere to turn.

Last year, Grameen opened a branch in New York City's Jackson Heights, an immigrant enclave just miles from the global center of finance, Wall Street.

Yunus says the financial crisis offers an opportunity for businesses, banks and governements to revolutionize, and create a fairer economic system for the world's poor.

Send your questions for the banker with a conscience below, and we’ll do our best to put them to Muhammad Yunus, our Connector of the Day on Wednesday.
