Day 6- A person you would love to trade places with

So this one I also found a little hard since there are people that are athletes and celebreties that I like but would not want to trade places with. So my choice is a little random....

But if I could trade places with someone I think it would be pretty cool to be the fastest person in the world for one day which is Usain bolt. I wonder what it feels like to be that fast, and to have a body like that, hello leg muscles!
