I've been feeling slow and stupid lately (no thanks to
this guy and
this guy).
I should at least get around to
joining the gym:
"Exercise boosts brainpower by building new brain cells in a brain region linked with memory and memory loss...the dentate gyrus, a part of the hippocampus that is known to be affected in the age-related memory decline that begins around age 30 for most humans".
Although maybe it'd be easier to welcome the inevitable and just retire now.
