Is it Latin? Do you mind saying the exact phrase and it's literal translation? Also a source, if it has one - just curious about what impressed you to the extent of permanently marking it on yourself.
Yes, it's Latin. My tats almost all have Latin, except one or two, with Ancient Greek and Old Norse.
I am the source. I studied Latin for a long time.
Latin=vive et dimica de vita sed memento ut olim tibi sit necesse mori.
Literally= live and fight for life but remember that one day to you be must die.
Better=live and fight for life but remember that you must one day die.
