That's a grey hair you have, but don't worry as it's a sign of wisdom.

It's also a sign of getting old, too.

Memphis Grizzlies F and known dunker Vince Carter is also getting old. So old that he has trouble dunking in the preseason this week when defended by two things: air and the rim.

Now Carter still does have the same ups as he's always had so maybe he's just in preseason form.

Either way, father time is catching up with Carter who has no plans to retire anytime soon, he's now been in the NBA since 1998.

Carter will turn 39 during the season in January, hopefully this won't happen in games that matter, or on national television.
