You look either silly or suicidal.
I know. lol. I'm wearing something that saves lives.
That doesn't look safe/You're gonna die, don't you know about CO2?
It's safe for me to wear. Yes, I know about the dangers of CO2. That's why my fan has a rated static pressure of 225 Pa, as outlined here.
You CAN kill yourself or someone else hastily emulating something this silly/suicidal looking.
There's something to be said about intuition, particularly yours in this situation.
What am I looking ...
