I feel like I've been hit by a couple of SUV's and only barely able to claim to be in my 30's. A few years ago I had an xray done and was in a room waiting for a doctor. This random guy walked in and asked my name, age, and if I had just had my scapula xrayed. He said He had to double check that nothing had been mixed up because my bones looked like someone in their 80's... Maybe avoid actually getting hit by those SUV's. My folks are in their mid to upper sixties, but I'm still the slower crochety one, unless I'm on a bike. For all you mid to old farts, there is a reason so many of us are on bikes. It may seem impossible, hell, I can barely sit up or walk, but it is amazing how bad of shape a person can be in and still ride a bike when it is properly setup and fit to the person. Without riding I fall apart both physically and mentally.

In other news, I expected the logarithm of day length verses lifespan to level out so that days seemed like a stable unit of mental measure, but the slowdown never happened and a day is an impossibly short amount of time.
