I train five days a week hard - but it is short and sharp - 30 to 40 minutes of functional and pretty dynamic body-strength circuits, then I do a good yoga session on the sixth day, then I rest.

I exercise about 40 minutes a day, and I'll run one day and do circuit training the next day. I live in an area where there are brilliant hills and mountains, so I get a good hill run with my dog. At home, I'll do the circuit training with old weights, along with pull-ups in the trees and that sort of stuff.

Sometimes it's hard for us to believe, really believe, that God cares and wants good things for us and doesn't just want us to go off and give everything up and become missionaries in Burundi.

I was christened Edward. My sister gave me the name Bear when I was a week old and it has stuck.

One killer exercise that's really great is pull-ups with your legs out level. That's my favourite. It's such functional core strength, and that's why I can climb up trees and down vines.

I do see a lot of the hard end of ecology, and my feeling is that we live on a super-exciting planet but a super-fragile one.
