We were told in Malaysia that monkeys fed by tourists are starting to suffer from obesity and diabetes – too much of the wrong food (and presumably, because they don’t have to search for it themselves, not enough exercise…)

And if that’s not enough to deter us, our guide explained that, in monkey communities, the alpha male is given food by inferiors. So they immediately rank anyone who feeds them as inferior and might treat them aggressively.

Ok, I’m convinced!
