The `Braveheart` actor - who recently became a father for the eighth time when girlfriend Oksana Grigorieva gave birth to daughter Lucia Anne - says he is always looking to improve himself and insists the best suggestion he ever received was to take up gardening.
He said: "Some of the best advice I was given, a long time ago, was from a guy who said, `You want to make yourself better, go and dig a ditch.` So, a lot of that-s been going on, ditch-digging, vegetable-growing."
The 53-year-old star also claims the biggest changes he has noticed about growing older is the effect it has on his sense of humour. He added: "The choices you make are just totally different because of maturity, male menopause, whatever outside influence is acting on you. You just look around and see, sometimes, that what you`d laugh at in 1970 is totally not funny now."
However, the actor doesn-t believe time has taken too much of a toll on his body. Speaking about playing William Wallace in `Braveheart`, he added: "He was something like 28 when he died. And I was already ten years older than that when we started shooting. But it doesn-t matter really, if you can sell it. At least my knees weren-t wrinkly."
