I’m a bit of a germaphobe as well. I bring a small bottle of isopropyl alcohol and tissue/wipes so I can do quick wipes of surfaces I’ll get in contact with for a significant period of time (i.e. restaurant seat/table, office desk, movie theater headrest if not wearing a hoodie, etc.).

I pull long door handles at the bottom because it’s the least likely to have been touched by lots of people or use my shoulder or foot to push open doors.

I keep hand sanitizer handy as well. I sometimes have to stop myself because I instinctively grab it out of my pocket after shaking someone’s hand, and I don’t want to look rude so will only sanitize out of sight.

I don’t feel paranoid at all because it’s routine to me and I can live my life normally without it being a hassle. Just take minor steps to make yourself feel a little more comfortable, it doesn’t have to be all or nothing.
