Just wait till you're 60. Your hair loses pigments and you become an old guy.
Then again, you can always just dye your hair white.
Try something new. Go to a hairstylist and ask them to dye your hair pure white.

Do something out of the ordinary, extraordinary. Don't be regulated by society, fuck society. Pull life in the direction you want. Fuck your image, don't dictate your life based on rules.
