Maybe next you should buy and Autoclave to make sure your silverware is sterilized, you know because other people have eaten with them?
That's what the sterilize feature on a dishwasher is for
Heck why not just install some UTC lights all over your home, because if you think you are helping yourself by just cleaning your phone you have another thing coming! Give your head a shake and go back to your bubble.
I have Multiple Sclerosis. Do you know what a stomach virus or the flu would do to me? Of course you don't. It appears to be beyond your grasp to think there may be someone out there that might have different needs than your own. You seem to see things in black and white...no middle ground. No one thinks that cleaning one's cell phone would eliminate all germs from your life but there is a very good chance it would certainly help. And yes, I'm one of those weirdos that wipe the Walmart cart handle with the provided wipes. How stupid on their part! If more people got colds, the flu or stomach virus, they'd sell more medicine. I (not as often as I should) wipe the steering wheel of my car. I have Tapmasters (turning on/off water with the press of my toe against a plate attached to the toekick) installed at all the sinks in my home. Not only is it uber convenient and increases workflow, but it prevents cross contamination with things that can cause food poisoning and other illnesses. Hospitals must consider this important since they use them as well. And the best line of defense, I wash my hands several times a day. I'm not a "germaphobe". I'm practicing common sense!
If you have children, I feel sorry for them, because paranoid germaphobes like yourself that feel the need to sterilize your cell phone, are the same people that have kids with massive allergies, because they are pampered and babied and not given the chance to build up an immune system.
Oh for the love of Pete! I hope you're not teaching your children (provided you have any) to be as rude!
