Usain Bolt has suggested a career in action movies or football could beckon after he retires from athletics.
The world's fastest man will hang up his running spikes after this month's World Athletics Championships at the London Stadium.
The Jamaican, who has eight Olympic Gold medals to his name, is expected to once again dominate the 100m and relay.
When asked by ITV News Sports Editor Steve Scott at a press conference on Tuesday how he would replace the adrenaline rush of being the best in the world, he replied: "I don't know what I'm going to do. This is why I think I wanted to play football to change it up, get a different rush.
"We'll see where life takes me. You never know in which direction I might go. I might go into acting and do some action movies. You never know."
- Bolt's career in numbers
Bolt's legacy is assured, even if he is due to hand back one of his nine Olympic medals - 4x100m relay gold from Beijing - due to Nesta Carter's positive drug test from 2008.
Last summer in Rio Bolt ended his Olympic career with three more medals, defending the 100m, 200m and 4x100m crowns he won in London.
This year he returns to the capital knowing he is as revered in the UK as much as anywhere else in the world. And Bolt said he is particularly looking forward to performing in front of the "number one" crowd.
- Usain Bolt on the London crowd
"I think the two best crowds I've ever had were London and Beijing the first time I went (in 2008)," he said.
"I think those were loud and exciting crowds. I think London was pretty good because the reason being that they came out even in the morning session.
"The stadium was always full and I've never ever seen that before, so for me I would definitely rank them number one for sure."
- Usain Bolt on who will replace him as the world's fastest man
As for who will replace him as the fastest sprinter in the world, Bolt refused to say.
"I'm not going down that road," he said. "The last guy I said was going to be great disrespected me so I'm not gonna say who is gonna be great.
"I'm just gonna leave it to whoever shows up and is willing to fill my shoes will fill my shoes, so we wait."
