I have family members that were iron workers.. I asked one how he did it and he said "I don't know" with a really somber face. They lost a few dozen guys on one project and he found a different career. The other one fell off stuff, drank the worst wines, smoked the worst cigarettes, was homeless as a teenager, etc.. had a really hard life iow.... Last we heard he was in his '90's!!
Must have been a windy day. Surface tension is less when it's windy. If you want to jump off a bridge to kill yourself, do it on a calm day.
