I can say this now since I’ll be 49 in a few weeks (my God): Back in my day, the Steelers season just ended, and then I would go on to do a bunch of other stuff.
Some examples: Daydream in school; play video games; get made fun of by girls for wearing sweatpants to school; ride my bike; eat junk food; get made fun of by girls for wearing sweatpants in the summer.
Sure, I enjoyed a few football-related events in the offseason, including the NFL Draft and the occasional NFL Films show that popped up on some random channel at some random time.
