Bad times with tear gas or other chemicals, heard stories of people getting them stuck with things like acetone vapours alone on top of it probably making it harder to rinse your eyes.
Honestly, people should be preparing with full face respirators that they’ve practiced using (and they’re useful to have around anyhow)























Back in my first year (2008) we had these mandatory online assignments for physics and calc (think it was springer or something). Some of us would group up to work through things which ended up making our study groups. One of my friends at the time used to do all of theirs in excel and upload them (I was in residence at the time and there was a gigantic peer to peer filesharing network on campus) for everyone to use, I know there were a ton of people who didn’t even touch the homework without them.
It’s definitely not a new thing for sure.
