Level. Like in a video game. Don’t you think of the lifespans of your friends in family and terms of video game levels?

No. Leveling up implies some sort of growth or improvement. We all know people where one year older doesn't mean they leveled up.

Level in games doesn't necessarily correlate with skill. People can build their character badly and end up with subpar skills for their level.
