Generally speaking, I don't watch the YouTube reviewers.
If I buy a new atty I will find one wicking vid and that's it... I skip all but the wicking section of the video.
I avoid the weirdos - at all costs. If a reviewer is loud and obnoxious, I move along to the next review. I won't sit through crazy.
I don't care about these reviewers lives, who they are married to how many kids they have or what they eat for breakfast. I'm not I invested in their life, and they aren't my freind.
I just want a heads up on wicking. ... nothing more nothing less. If I want to know if something is any good then I find out from people who own the product and have used it more than once.
That said, the nut job in question seems to be at a healthy weight for his height, although he could stand an additional 10 pounds for his age. He's not 18 any more. I'd look sick if I got my waistline back to a 25 to 26 inch waist... why? Because I'm not 18 any more. (im almost 5'8")
He is small boned so generally speaking he's fine though.
It might be more shocking to those who saw him heavier but bone structure matters. My son at 5"11 has a healthy weight of 200 lbs. He is large boned and solid muscle... he would look sick any other way. My husband on the other hand is 6'2 and around 165-170 lbs, and is solid muscle, but not muscular in appearance like my son is. He is smaller boned, and is at a healthy weight for his build.
So, bone structure and build matters. Same goes for the nutjob in question.
As far as my taste in reviewers - some people find bat### crazy amusing, others dont. I'm just in the later category - not judging.
