Hair=Youth

Sorry for stating the obvious but it is the truth.

I would just say guys I see getting carded for being 21 or even 18 at a casino almost always are like NW 0 or maybe a 1 it makes a big difference in how old you look because most men as they age do go bald so men that dont stand out that much more.
Since there is no cure you can judge a mans age by his hair line a lot of the time I do it a lot myself. If your high norwood most people guess your older regardless of your actual age. So in my opinion hair loss is important even though a lot of people shrug it off as no big deal.
