If fresh chilli is part of your recipe, you really, and I mean really, want to go to the loo first and only then chop your chilli. After washing your hands thoroughly, of course. The other order is a bad idea. This advice applies definitely to males. I cannot comment whether the female experience is similar.
I’m almost chilli immune. But just, once in a while, I forget and rub my eyes.
Wash your hands, people. In yoghurt!
