Definitely good about bananas - a little trivia about bananas: a natural way to treat warts:
Banish Warts with Banana Peel - I tried it, it works! It takes a long time, about 2 weeks, and you have to use a fresh peel from a ripe, but not overripe banana, so doing the treatment, you eat a lot of bananas. All you need is a snippet of the peel to apply with tape over night.
washing hands - if my sister sees that advice, she'd scrub until her skin comes off! Myself, I think worry is far more dangerous to your health, lol - I told my sis to build up immunity, she should lick the handholds in the U-Bahn - and guess what: she is the one that always gets sick, but not me.
Coconut: as some tourists to Hawaii have found out, but ever since they sued, there is barrier tape around the palms until they cut the coconuts off. Woman injured by falling coconut tree in Waikiki gets $1M
