A saggy Hammock, you could get stuck in there and die of thirst!!!
I also remember me and my Ex wife had split and on a visit to see her a couple of weeks later, I thought her hair was looking very modern and spikey with this new wet look style, so to cheer her up, as I had previously never noticed her new hairdos I said, " You've had your hair done, look great" BIG MISTAKE!!! she screamed and walked out, I was later informed that she had just applied a treatment for head Lice! :-)
That was fairly hazardous!!!!!!!
