Funny, I never thought about it this way. I have a niece who's a woke leftist attorney for the trans-alphabet-people. She's Jewish, so, of course, she married a mooslim lesbian who heads a foundation to teach the world how isloom is really 'kind' to gays. At a lunch, when Trump was in office, she began railing against President Trump, and she was shaking as if she were about to have a seizure. She is a vegan who, I believe, only eats things that 'naturally' fall off a tree: Nothing plucked pulled or cut can make it into her gullet. I just googled it and they are called Fruitarians. Needless to write, she looks like a skeleton. I thought her shaking and aggressive behavior were due to the fact that she's bipolar who suffers from food issues (she's been an anorexic who has had to be hospitalized). But, it's very possible this dietary deficiency could be causing the shaking. After she screamed at me when I said the only beneficial thing Hussein Osama ever did was to pave the way for Trump, she shrieked all sorts of expletives at Trump, to which I reminded her that there are many choice words one can use to describe Hussein Osama, and his mate.

Could be around 23-27, but looks ten years older, the typical "Male Gaunt Vegan" Face. Probably hairline is receding prematurely as well.
