Raise your hand if you remember the days when having three or four nights of little/poor sleep just meant you might have to take a nap during the afternoon to feel refreshed. I’m so jealous of my younger self right now because my current self is both sleep-deprived and an idiot. Just having a few restless nights would be one thing, but I also had to wake up early for a Thursday flight and then did a four-park Disney blitz that included over 22,000 steps.
I must say, however, that I much prefer that kind of tactical approach to the one-park-a-day slog.
