WHAT DO YOU KNOW NOW THAT YOU DIDN'T KNOW IN YOUR 20s?
EWAN MCGREGOR, star of "Star Wars" and "The Impossible" on how to staying healthy and how to stay fit
He says: "I know that it's important to remain active no matter what. I think we take that for granted when we're younger, but when we get a little older you have to make plans to move.
"I'm quite an active person, but sometimes I'm in towns where you don't have a place to move, so it's easy to think, 'Forget it.' I know you can never do that. You can walk miles around any city. You can walk hundreds of miles, and it keeps you healthy and feeling great.
"So, get out of your car. You don't have to make a big gym plan. Just focus on the natural burning of calories through walking. I also like to cycle because I love the subculture of bikes. I run.
"I'm pretty much a stranger to the gym. I don't like working out in a gym. It's not my thing.
"But I do like the feeling I have from moving, so I take any little bit of time. Let's say I just have 20 extra minutes. That's the perfect time for a bike ride or a walk. It becomes an adventure if you do this outdoors. Who knows what you'll see or who you will meet.
"I don't like to walk or cycle in my house watching TV. I tell other people to get out there.
"Life should be an adventure."
