Do future you a favor: Stop abbreviating things in code.

Characters are free.
Lines of code are cheap.

This has the added benefit of helping people without your exact experience to understand your code, too.

Count Dracula was 412 when he moved to England in search of new blood.
Sauron was 54,000 years old when he forged the One Ring.
Cthulhu had seen galaxies flare into life and fade into darkness before he put madness in the minds of men.
See, it’s never too late to follow your dreams!
