Lord Beetus isn't as fast as he should be sometimes.  Can confirm. My family has amazing genetics (very long lives, Nazi eugenics program attractive, very few health problems generally) and is full of 60-70+ year old obeasts, alcoholics and junkies. My grandfather is 70 something years old, 5'8, around 300 pounds and a lifelong alcoholic, and it looks like he still has quite a few years left, barring something like inoperable cancer.
