If you eliminate your ignorance, you'd actually know that that video was quite interesting and very informative and actually learn something. Because that video is very in depth and I'd be surprised if you knew everything that was said in that vid.
The very fact you took the time to highlight this gentlemans age, tells me you disregarded everything he said just because of his age. Which is highly disrespectful, by the looks of things he's in his late 20's if anything.
Side note: "Millennials" is anyone born between 1981-1996 so you can be a Millennial at 37........
The term Millennials is a crazy one, calling them spotty millennials, which ultimately brings connotations of the word with: no real career prospects and don't know hard work if it hit them in the face, or can't stand losing/understanding the real world....but who raised "Millennials" ??? hmmmm
Irony is that that silly "YouTube video" probably took at least 40hrs to make. But hey..."Spotty Millennials and there YouTube eh?"
