This actually happened to me last m month:
I have had hip surgery and the recovery is not going well. I still walk with a cane, sometimes two, I go to physical therapy and visit a gym on my own.
So I was at the gym. The place is crawling with much younger healthy and fit people. Many are wearing outfits that are are so tight you can see their, umm, err . . . . .their tattoos.
I used the floor mat area for some stretching before doing some resistance training. I started to get up off the floor in my awkward way. Before I could blink, there were two strangers helping me get up. One was a hulking,hairy bruiser training for an MMA bout. The other was a 95 pound twenty-something woman . .. Bigfoot and Tinkerbell!
That tells me I am getting old . . .or I'm already there.
