Schoolchildren and older people like the idea of planting trees. For children, it's interesting that an acorn will grow into an oak, and for older people it's a legacy. And the act of planting a tree is not that difficult.

On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.

It's true, people don't imagine I'd be particularly woody.

I am attached to the west coast of Scotland - it's gorgeous to look at and challenging. You have to contend with the possibility of being blown away or rained on. And in the summer months you can be eaten alive by midges.

I do find myself surprised by the comedy shows that seem to have the same joke week in week out.

If I ever had any vanity, then I definitely lost it by being on television.

I have done well out of TV, but not well enough to buy football clubs. I'm not sure it's ever a way to make money.
