Can't touch this

When ever I sit on the subway I make a concious effort not to touch anything with my bare skin. I'll use a glove or a sleeve if I need to hang on but if I can help it, I don't put my bare skin on it. To justify my phobia I noticed today someone standing next to me picking his nose. Of course the first thing he reaches for after finding gold is the subway bar to hold on. Now, he's just one guy. However, I see him and I can't help but think of the millions of people a day that ride the subway and how many of them are searching for gold in their noses as well. They inevitably reach for a part of the subway car to hold on to. This is probably the grossest thing I can think of because these nasty people are out there and they are touching everything. I'm thinking of becoming a bubble boy. It might be the only way to avoid such problems in the future.
