From Elaine Chaney's piece, "7 Unexpected Moments That Remind You You're Getting Older"...
Imagine getting hammered, going home and just falling asleep on the floor, the recliner, the bathroom floor, a throw pillow or in an impossible position, and actually sleeping? I did this more times in college than I can count, and I remember waking up the next day feeling just fine. Now, sleeping on a futon is like a nightmare. What sadistic weirdo thought sleeping on something that's barely thicker than a sweatshirt was a good idea? The last time I thought I could pull off sleeping on a futon, I woke up the next day and felt like I had gotten zero sleep. There was also a wonderful pinching/numbing sensation in the middle of my back. What the hell happened?
Read Chaney's full piece here.
Being almost 40 happened. An age when sometimes even your bed isn't comfortable enough, and you get a serious crick in your neck if someone steals your firm pillow (looking at you, husband dear). And as for feeling refreshed after a couple hours of sleep, that has become such a distant memory that I'm not even sure it was a real thing to begin with.
