Back when I was younger, traveling, the dirtiest things I touched other than money, were bar table pool balls in the south (N. Orleans), and billiard room pool balls that were NEVER cleaned. I used to pick my nose, scratch my inner ear at times and on. I always exercised my entire life, ate well and my immune system only gets a bug once every 4-5 years. If your never exposed to any germs, and you duck em every chance you get, well they get stronger every year, and by not being acclimated to the ones before them, your even more prone to getting even sicker.
I used to say, ''it's fun being sick for a few days'' because its something different. But lol, after about 12 hours, I don't like it. Only once in the past 35 years was I not able to beat the sickness 100%. I got a Z pack, and it was gone. I do tho eat at least a dozen oranges a week and a gallon of OJ minimum, just cuz I like the taste.
I will never wipe the handle bar of a grocery cart. But I will always wash my hands before I leave a public restroom, ONLY by grabbing the handle with a clean paper towel or Toilet paper.
