re: How fast can hair go grey?

It's strange to me people going gray so young. I'm almost 54 and only have a few in the beard. I can cut them out and have none on my head but eventually this will have to stop unless I color it because I'm not shaving it. I can't see coloring it unless I plan to stay on top of it and even then it may look stupid.

I don't have kids or a stressful job which I think are the biggest contributors to fast graying unless genetics say f you.
