Shop NYC Top

I’m 72 years old and still working and commute into the ‘city’ from Brooklyn three times a week. I have been a regular subway rider for my entire life. But in the past two years, I’ve noticed that almost no one is as old or older than I am. Of course, I’m guessing their ages but I give everyone a wide lattitude. I count people who could be my age or older and NEVER get up to 4. Mostly, it’s 0. I wonder why this is. My guess is that everyone my age is retired or just not up to climbing all those stairs. What do you think? (BTW someone gets up to give me their seat around 20% or the time which I appreciate.)
