I used to.
Seems I was sick all the time.
Now, I avoid door handles, the railing on stairs, even the elevator button. I use sanitizers all the time .. even rubbing some on the handle of shopping carts!
Whenever I go to a store or an appointment I sit as far away from people as possible. This is a biggy: I'm terrified of kids and will do anything to avoid them as they seem to carry germs the most.
I also started taking Vitamin B and D. AND always get the flu shot every fall.
Precaution is my mantra now...good luck to you.
I hope you win at this battle.
