Is it safe to jump up and down in elevators?

@Sunny_Daze, that mom guilt is all too familiar, and often enough the kids hardly remember whatever we did. Many times I heard my aunt say that she felt very guilty that she’d let my uncle drag my hippie cousin to the barber and cut his hair short, back in 1970. When I asked my cousin if he remembered feeling bad about it, he just laughed and said he’d practically forgotten it.

About elevator jumping, I don’t remember ever wanting to do it, and not for lack of exposure to elevators–from ages 3 to 9, and then again for 6 years as an adult I lived in elevator buildings in big cities. I don’t remember ever seeing anyone jump in an elevator either.

Wondering if I’d just been missing out on a cultural phenomenon, I asked about it in the Polls only thread, and it seems that the majority of respondents haven’t seen it or done it. Of course, so far there are only 38 replies, but at least it shows me that I’m far from the only person who doesn’t jump in elevators and hasn’t seen others do it either.
The current poll results:
61% I have not jumped up and down in an elevator and I have not seen any other passenger jumping
18% I have jumped up and down in an elevator and I have seen at least one other passenger jumping
16% I have jumped up and down in an elevator but I have not seen any other passenger jumping
5% I have not jumped up and down in an elevator but I have seen at least one other passenger jumping
