I never did dunk on a 10’ rim. I could touch the rim, could occasionally get a finger on the top of the rim, once upon a time I got the middle of my hand on the rim, but even with a 39" vertical jump there’s something about being 5’10" limits the actual chances of a dunk.
And I have the same thoughts about running a 5-minute mile, that yeah, if I can get through hip surgeries and rehabbed and built back up, I can do it but realistically I know it’s not happening. No idea what I should be shooting for - I think at first, it’s just “run a 5K without stopping once” - but I’ve got probably a year before I can worry about that.
Neither one is really a disappointment, more of a “that would have been great, but I’ll be fine without it” kind of thing.
