Ok, I'll keep that in mind.
Travelling has also given me the chance to experience a big variety in food, if you're in a place for instance offering lots of different good options... India for instance would be harder I guess than south east Asia, as in India most food is based on Dalh (lentils), chapatis (bread), rice and curries (with huge amounts of rice and little veg ) and cooked dairy. I also find that Indians in general have more grey hair than south east Asians. There is (in general) more poverty in India than in South east Asia. It's true that there are quite a few people with bad teeth in SE Asia, but in general I would say that in India, loads of people are without front teeth. My point is that in Laos for instance, they eat lot's of different strange things :bats, grubs, frogs, ducks, everything from the buffalo, all sort of Mekong-fish - from tiny ones to huge carps, and they seem real healthy...
I can imagine it must sometimes be quite challenging to travel, not necessarily far away, as you would need either to bring your own food or make compromises...or fast...
