The trees pursue a branching algorithm
They start out stout but end up long and lissome.
I gave blood tonight. I suppose blood vessels make use of a branching algorithm too, and it's a good thing, or we'd never get blood to all the places we need it.
Anyway, I've done 2 clumsy things now, so I guess I'm feeling the effect.
Blood is fun for me and for you -
It's red and it's slippery and full of O2.
