More vacation days (probably depending on your union, but at least where I work the older you are the more vacation days you get).

Can start looking forward to retirement maybe?

People don't follow me on the street or interrupt my day to try to chat me up. Though soon they'll start doing it to scam me instead, so staying sceptical.

A lot fewer people stubbornly mistake my friendliness for flirting.

I'm more aware of my limits, and people tend to respect it faster when I set boundaries.

Though I'm early in it, so there's more to come for sure.
