I turned 30 recently, which means I'm no longer young.  The opposite of young is old; hence I am now old. 

I was sitting at my desk on Monday morning, and kept noticing various parts of my body which were in pain.  This isn't too uncommon; I occasionally work out and sometimes even do hard physical labor.  But it had been a while since either of those two occasions happened, so I was sitting there trying to figure out exactly what I had done to cause this specific pain.  The front of my neck hurt, almost like whiplash.  I was racking my brain trying to figure out what activity could've caused whiplash.  Did I fall on my back at some point on Sunday?  Did I not use my legs when I lifted something, instead somehow miraculously using my neck muscles?  Did someone push me down the stairs? 

It finally came to me:  I slept in, and at one point, I must've been laying face-down on my pillow.  That's right.  I injured myself sleeping.  Welcome to old age. #health
