I wear a mask at work 8+ hours a day. It’s not unusual for me to log 10,000-15,000 steps during that period. No big deal.
If someone can’t wear a mask for the few minutes a day they may be in public, then they are major pussies.
Whenever I take public transportation, or get on an airplane, I'm going to mask up. Frankly, it's something I should have done ages ago. I used to always give those folks who wore masks on planes funny looks, but I was wrong to do that. Now, I totally get it.
