If you look at it ecologically, deforestation is high on the list of things which bring devastation. You cut down trees to build homes, for fuel, and you end up with no trees left, and you have to move on. If you take the earth as a whole, eventually there's nowhere to move on to.

My favourite plant is the foxglove. I think they are a perfect balance between being a garden plant and a wild plant, as at home in woodland as they are in a city.

I try to make myself walk around a bit, but I probably think about it more than I actually do it. Years ago, I did think about joining a gym.

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

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.

I'm not bald. I'm just taller than my hair.

I don't think I'm really a rude person, but now I see myself on television, I think, 'Oh, God, that is a bit strong.' And I wonder if I've always been like that and I haven't been aware of it.
