I am a bit obsessive about the natural world and natural history. In the event of an apocalypse I'm the man you want, as my knowledge of wild foods, herbs, etc. is vast - we'd be fine while everyone else is fighting over the last tin of dog food left in the smouldering remains of the local supermarket :o)
Sport bores me, so there's no need to pretend to be interested in football, etc. I have got into martial arts and surfing in the past, but not into competitive, team sports - maybe a bit of test cricket.
I am in good shape though - I'm self-employed. If I don't work, I don't get money. I do alot of physical work and having a good body is a side-effect of that - I'm not a gym-junkie type muscle-man though!
