Pure anecdotally here, but as im getting older death seems more and more significant and possible and to be feared. Im only in my 30s but somewhere along the line i picked up a self-preservation instinct.

As a kid/teen i was going to live forever. I couldn't die. The biggest fear was waking up in hospital but even that was farfetched to one as invincible as me.

Nowadays though im perpetually aware that one slight misstep could bring me down skull first on a roadside kerb and it could be game over.

Wrong side of my 30s.
