I found a lone bandit to keep shooting arrows at my shield and improve my blocking. I back off, use the magicka heal, wait a while use the magicka heal, wait while, heal, okay go get shot some more, back off, heal, wait for recharge, heal, etc.
Then I realize I'm really wasting lots of time merely waiting for magicka recharge, for a critter I know isn't going to kill me. So why even let the health drop at all? Fine, TGM it is. Block, block, block, block....
Then I realize after a while I really don't need to be sitting here actually doing this. Just pin down the block key with a weight and come back in an hour or four when Block is at 60 or 90 or something.
Then I realize... was I playing a game at some point along here? Dunno.
