Malgus good call on humor. There is actually medical data backing up the healthy affects of humor. I won’t list them here. Laughter is often a natural reaction to a stressful situation. I was working about 180′ up on a steel platform one time. We had to rotate it. Something came loose that wasn’t supposed to and it spun 180 degrees in a split second almost throwing 3 of us over the handrail. Banged and bruised, all we could do was laugh uncontrollably laying on the grating.
