Mark is the head of Lush cosmetics, the chain of beauty shops that smell so strongly that they put many people off. He once explained that this intense smell is due to the fact that the company uses either little or no packaging and so the aroma is free to roam. With Anita Roddick, he set up the Body Shop and was the originator of its no-animal-testing rule. He doesn't drive, doesn't eat meat, and funds numerous road and aviation protest groups around the country.
When I interviewed him a while back, he asked if I would let him into my bathroom to poke around the bathroom cabinet; I said no extremely firmly, but then he asked me again and, finally, I gave in.
