Among a number of different candidates, I’d have to say the worst part about getting older is that you don’t heal very quickly. Even superficial injuries like bruises or muscle strains become prolonged encumbrances that can last for weeks on end. As I type this, I’m moderately hampered by a jammed left pinky finger that has me looking like an undersized ex-offensive lineman for the last three weeks. All because I caught a football awkwardly.
What makes it even worse is that our bodies become an actual version of the ubiquitous gag where someone tries to plug a leak in a dam, which only leads to more leaks.
