My FIL was the “youngest” octogenarian I’ve ever met. He had a full Navy career and then another full career as an MBTA driver. In retirement, he drove the Senior Center bus on trips and he was usually older than the people he was driving.
He also owned a nice suit and always had well polished shoes (as I said, a full Navy career) so had a deal with the funeral home to be an on call pallbearer if families didn’t have their own.
