Dawg, you can easily look at someones hands and know if they are manicured. Especially a man.
Ill put it this way, limited resources = limited mindset.
When you have multimillions in the bank and you hang around with others who have as much and more than you, you have a different mindset. You do stuff they do, go places they go, etc. There's a reason a bunch of rich ppl hang out in Aspen, Lake Tahoe, etc. There's a reason most rich or famous ppl "look" like they have money. When you see their face, it just looks different....because they use the best/most expensive of everything. They're not using Zest soap on their face, breh.
As far as examples, I know for sure Michael Irvin has a "spa day" that he does(mani/pedi/massage, etc), and Emmitt Smith everytime I've met him has hands soft as a babys butt. I know other dudes I went to college with who are in the NFL now, samr thing.
Their hands/feet make them millions of dollars. You'd be an idiot not to take care of them.
And if yuo read articles about appearances and how to appear to have money, one of the things it tells you is to have clean, manicured finger nails and hands. Google it if you dont believe me.
