It's like wearing a bulletproof vest all the time because you might get shot one day. What's the point of making your life harder just because you're a scared weirdo?
I wear a mask in stores just because it makes people more comfortable around me and I don't want to make a scene. I don't believe it helps in any way because I'm not sick and won't spread the virus and I'm also not afraid of catching it. I know people who had it and the only symptom they've experienced was a headache. So, I wear it for others not for me, but I'm not going to wear it everywhere, that would be a huge burden to ride a bicycle or walk on a hot day with a mask on. They tried to enforce it like 2 months ago but most people were ignoring it. We even had the police chase people around for not wearing masks, trying to fine them.
