Every time that I renewed my Commercial Class A drivers medical and 3rd Class FAA medical, I would get a new set of calls and letters for job opportunities.
I called one of the largest companies, who had been contacting me nearly once a month, and asked them to take me off their list, as I was 70.
The response surprised me. They are intentionally recruiting drivers that old.
They show up on time, every scheduled day
They show up sober every time
They drive slower, get fewer tickets
They do not get complaints from the public about continuous left lane cruising
They spend more time on cruise control, which saves gas
Negatives
They do take long vacations, several times a year, but let you know in advance
They do take sick leave more often
Some have a preferred shift, which is not negotiable
Like younger drivers, they want to be back home regularly
They are not going to fake their hours to run in excess of the rules, no matter how important the customer
One of my wife's work friends took up truck driving after retiring at 60, earned his class A commercial, and drove to 75
I never responded to any flying offers, as I was never willing to fly at someone eases convenience, there is too much weather decisions that must be made that result in flying in perfectly legal weather, but marginal safety wise. I was too old and wise to get into that part of life.
Flying someone I knew, in their plane, because I had the IFR capability, and they did not, continued to be fun, though.
