I kickbox now.
It is the most amazing thing that I've ever done. It's hard, but it's straightforward. It's like physical origami - the actual thing you're doing is simple to understand, but the execution is ridiculously difficult.
Block from the outside in. Parry from the inside out. Four steps to every kick. Pivot the foot that's not kicking. Keep your hands up. Don't lean in to a punch. The front hand is the speed hand - the back hand is the power hand. Shuffle forward, shuffle back.
I also run now.
Something else that is incredibly simple. Walk. Then go faster. Then go fast enough that both feet are off the ground at some point in each stride. Don't stop. Until you're back home. Then stop.
I'd stretch, but I'm not that into not being injured.
I did my second 5k today. I was too sick to do it, but I already paid the entry fee. Therefore, I threw up. Somewhat distressingly, my time for 5k-where-I-was-sick-and-threw-up-next-to-someone's-honda is 6 second shorter than my time for 5k-while-healthy-and-not-vomiting.
I also just moved.
Something that seems incredibly simple - find all stuff in apartment, shove into containers, convey to new place, remove from containers - and is in fact incredibly complicated.
Find stuff. Identify stuff. Sort stuff which is meaningful from stuff which is actually retained trash. Sort stuff again into stuff which should occupy new apartment, and stuff that should be shoved into the basement of new apartment. Identify analogous locations for all stuff once conveyed...very, very difficult. Exhausting.
If moving were somebody, I'd punch it, and kick it, and then run away from it - if it ever threatened me again. But, unfortunately, it's a process, not a person. Processes cannot be punched in the kidneys, and running away from moving is actually just making the affirmative decision to either become homeless or never, ever, ever move. Which is hard when one isn't a homeowner.
No real point.
Seriously, though - if you ever get the chance, try kickboxing. No matter who you are. No matter what you ordinarily like to do. It's like...1.2 times as fun as making cookies. And that - is my highest endorsement.
