(1) The place where the legs attach to the rest of your body so you can keep walking. The tip. The top. The tippy-top part.
The last chance for things that were meant to be together to share quality time.
Where the body forks. (As if you hadn't known since grade school.)
Occasional summer home of monkey nuts and crotch rot.
(2) The part of a turn where the turning happens. The sharpest part.
Before the apex you are entering the turn and afterward you are exiting, whether you like it or not.
This is quite a bit like life which can also suddenly be over just when you feel you're finally getting the hang of it.
This sort of realization is especially disappointing when you discover that you are not only on the way out but also have a burning fungus problem in your apex.
