Memento Mori and Memento Vivere. Remember you'll die and remember you live.
In the ancient Rome, Memento mori was something a killjoy use to say to the victorious generals returning from battle to be sure he was not too full of himself and probably because the killjoy was one of those dudes who must be fun at parties.
In our time this terms are usually used by pseudo neo-gurus of stoicism, fitness, business and such but overall is a good reminder to not waste our life and make something useful with our time. For example, not wasting your precious time designing a weird coin and keychain.
The coin is and the keychain are splitted so it doesn't need supports and intended to be pasted later. This opens the possibility to do one side mori and the other vivere, double mori if you are fond of dead, double vivere if you are afraid of skulls....
Have a nice day!
