Memento Mori is from the latin reminding us to remember death because we all die. But it will not be from dehydration if you have this kick ass 30 oz laser etched tumbler. And since it's double walled, vacuum sealed and comes with a lid your drink will stay hot or cold as long as you are alive to drink it. And if you happen to see the Grim Reaper approaching, this 30 oz giant, with it's tapered bottom so it's easy to grip and fit in cup holders, makes a pretty good weapon if needed. *Do not wash in dishwasher.
