I think there are other things out there. Retire, fly for fun at the local grass strip buy a sail boat, restore a car or built an ultralight out of a kit.....
There are other things in life beside flying 100 tons of metal from A to B and then sleep in a hotel just to get back the next day.
Make room so cadets can make F/O, F/O can make captains, captains can make instructors. I guess you were all cadets one day too.
You can`t stop the time.
