They are 33 this year, rapidly approaching old age themselves.

Maybe twenty years ago they introduced a new product line that I thought was clever. The idea is you dye your hair with an inefficient dye, so after one dye job you still have a lot of grey left. You keep applying it over and over until the grey is gone, so you don’t just show up full silver one day and jet black the next. You just age backward for weeks.

That was "Grecian Formula." They don't make it anymore because it colored you hair with lead! It looked like a clear liquid, but the lead in the lead acetate it contained would bind with your hair, gradually darkening it.
