I also shake strangers hands and eat food made by teenagers and use public bathrooms and pet cats and sleep in hotel rooms. My children (if/when they occur) will attend daycare and school with other sacks of disease and share the spoils with me, as is tradition. Our society is dirty. Do you avoid handrails and sanitize the doorknobs and gas pumps you interact with? Those are going to be far worse than subway chairs. It's probably not a bad idea, but it's a bit beyond what I suspect most people consider normal. I had a friend who lived like that, and he ended up being diagnosed with OCD.
