What does it say about our society that it has invented this, the portable armrest?
It’s a mini-straightjacket-looking thing that you slip over both your elbows. Voila! Instant armrest, without worry about accidentally coming into contact with the human being sitting beside you.
I have not tested this product personally, because it looks stupid.
