Why do Black people think they look younger than White people that are the same age?

Black people try and say they age better than White people. Look at Bob Cosby, he is 71 and looks 91. Red FOX looked 80 on Sanford and Son and he was only in his early 60's then. The Black actor that played in Shawshank Redemption, or what ever the name is also looks his age or more. So, to sum it up, there are many of you people that look their age or older. Just keep putting that lotion on because I just bought 100 shares of stock from a company that makes loction for Black people.
