I'm good for about 10-12 hours, after 12 I start to feel it for sure!no, at 70 that 14 hour trip becomes two 7 hour trips over two days, with 5 pee breaks, lunch and a nap each day.
At 40 I could drive Atlanta to St. Louis in a day, now it tkes two days., and I used to do it annually now I haven't in 3 years.
Gravity is my mortal enemy.
