As middle-aged, it is very unusual for a guy in my age bracket to wear long hair, but I do, and I have done since I was 18. Personally, I don't give a shit what other people think, long hair sets me apart from the stereotyped military-minded Englishman who dwells in the past and mourns over the loss of the British Empire. So it was during my boyhood, and traces of this attitude still linger today. (Just buy the Daily Mail newspaper!)
At present my hair is salt and pepper, quite different to the jet black that was the hallmark of my youth. But I would never consider dyeing my hair back to its original color, even if it would make me look younger.
First, I'm proud to have salt and pepper hair.
Secondly, I grew up to believe that men dyeing their hair is - well let's say - effeminate.
Rather, I'm hoping that I would see into my seventies with a shock of silvery-white hair.
