I wear shorts and a T shirt just because we are "supposed" to wear clothes.
I like using organic materials first, but will use Malathion and Triazicide when needed. I don't ever spray on a windy day and I always shower right after using any sort of poison. I don't live where whatever I use could possibly get on a neighbors garden or anything else. For the poisons that I very sparingly use to get into the water supply - well, it's been a long time since we had an ice age or great flood.
