You joke but my dad once fell face first into a bonfire and blistered most of his face. When the skin grew back his dermatologist told him that a lot of people would kill for a skin treatment as good as what he wound up with. He was almost entirely blemish and wrinkle free when he healed.
You could probably manage the same with enough hot steam from an iron but it may take a bit longer.
I’ve never really wanted to be in the private jet billionare club but I have always wanted to be in the “have a nice paid off house and enough money to safely start a small business” club. Sure, being a billionare would get me that but what would I do with the other 99.999% of the money?
I’m willing to bet that they just didn’t want the legal hastle of collecting data on minors. Also minors are going to be more likely to lie about any potential sexual history.
As far a why they excluded man on man action I have no idea. If the origional graph was in an article about declining birth rates or something then that may explain it but idk what the original article was so idk if that is the case.
To be fair, neither are typically hand soldered in profesional environments anymore (outside of rework). Surface mount stuff gets paste and sent through a reflow oven. Through hole stuff gets wave soldered or sent through a selective solder machine. The only thing I can think of that needs to be hand soldered anymore are batteries because sending a lithium ion battery through a reflow oven or over a pot of molten metal is a bad idea.
Also, fun side fact, lithium ion batteries also explode if you stick then in antistatic bags. I’ll let you imagine how our inventory people discovered that.
