I have severe allergies and on public transport I wear N95 mask. It effectively filters out everything that might be a problem for me, and as a bonus have avoided getting sick even when everyone around me seems to be catching things. If everyone did this we could eliminate airborne viruses and many other conditions, but I’m not holding out hope for that.
This is my first post on Lemmy. Seems ok so far. I'm not going back to Reddit.
For a Twitter replacement I'm enjoying Mastodon. It's got a different vibe, more like Twitter in 2008.
