it's been a few years since I was in a Latin class, but I've been wanting to get a tattoo in the language for a while now, and "Remember death, but do not forget to live" is the phrase I've decided on.
Using what limited knowledge I still have and some googling, I've come up with:
"Memento mori, autem noli oblivisci vivere"
The fact that I'm using two infinitives in a row is setting off my "this is wrong" detectors, and I was hoping someone could guide me in the right direction. Thanks!
