I haven't heard of it and it is acool hot, as for claustrophobia I generally don't get bothered by small spaces at all, the only time. I got a little worried was stuck in an elevator, i Don't think it was the small space but more the fact the elevator had dropped what felt like 6 floors but was only two floors and no one was answering the intercom :)
Haha, a free-falling elevator is one of my biggest fears :D Probably because most of the elevators in Bulgaria are something like 30-40 years old. Thanks for your comment ;)
Most of the NYC ones are a lot newer just not in the building i work in the ones here are probbly as old as the ones there
Have a great day
