Thigh Gap: Some Things a Boomer Doesn't Worry About

So now that I'm retired, I sometimes amuse myself by thinking about stuff I no longer have to worry about.  Stuff that is Beneath Me.

1.  My watch.  I rarely have to wear one now, so when I looked for one, I found that most of them have dead batteries.  But so what?  Plenty of time to get 'em fixed.
2.  Panty hose.  At this point in my life, even if I'm meeting Pope Francis, I'm not wearing panty hose.
3.  How I look at the pool, even though there are two or three swim teams there.  Today, as I got out of the pool, there were about 8 teen boys waiting for their class to start, all standing there, seeming to be looking at me as I walked toward them.  Did I try to suck in my stomach? No.  Did it bother me that the bra part of my suit had lost a bit of elasticity?  Not really.
 As they all seemed to be looking my way, I didn't mind that they were looking behind me at some other kids they knew.  Figures.
4.  Thigh Gap.  Have you heard of this?  Now that I can jump around a bit on the internet, I've learned that girls now want to have a Thigh Gap;  that is, a space showing between their thighs, even though their knees are pressed together.
 I swear that I wouldn't want this gap, even if it were ever possible, with my rather short legs, to see much daylight between the thighs.  
 First of all, how short must your skirt or shorts be for Thigh Gap?
 Second, who wants people peeking through their legs for open sky?

No gaps for me--whether in teeth or thighs!
