Do what you gotta do. I also suck my thumbs to sample everything I touch. If anything it has made me immune to almost every disease. I have literally not been sick once in 20+ years no matter what/who I've been exposed to. I never get shots or see doctors. Even going to another crowded country like Japan, I never got sick...my friend was very ill the first ~2 weeks.
Maybe you should write a book or something. I shit myself for a week pretty much every time I travel. It's. Awful.
Last time, I LITERALLY came within seconds of shitting myself at chicago ohare.
