I'm not completely vegan - my diet's probably about 80 percent plant based, but I do eat some meat. I try to know where everything comes from, though. And all bets are off if my husband and I go to a really great restaurant.

I believe psychology has done very well in working out how to understand and treat disease. But I think that is literally half-baked. If all you do is work to fix problems, to alleviate suffering, then by definition you are working to get people to zero, to neutral.

All my grandchildren bake. On a Saturday, Annabel's boys, Louis and Toby, always bake. Louis makes a chocolate cake, Toby makes banana or lemon drizzle. They're 12 and 10, and they can do it totally on their own. My son's twin girls, Abby and Grace, are 14; they make birthday cakes and like to do it on their own with Mum out of the way.

I drive out to this quail farm, where I get a lot of these incredible quail eggs, which I eat all day long. And I eat a lot of superfoods like goji, cacao and chia seeds, things like that. And I like unpasteurised milk of the goat and the sheep. They send it once a week from Pennsylvania, from the Amish farms, and I get it in Los Angeles.
