But let’s suppose you look in the mirror one morning and notice a few changes. Those parts of your scalp that have become used to seeing the sun are now disappearing under new growth. And the beard you’ve been used to seeing as a distinguished 75% grey is now 75% dark brown and counting. And those familiar little creases at the sides of your eyes aren’t there, so you don’t look quite as (erm) distinguished.
It would frighten the bloody life out of you, wouldn’t it?
