Three of my sisters got jobs as cabin crew for British Airways in the 80's and initially loved the work. Nowadays they have to put up with increasingly awful, and sometimes dangerous, behaviour from drunk passengers on a daily basis. One of them has finally had enough and has just retired.
A few years ago, when I was recovering from an illness, I took a (solo) coach holiday to the Dolomites and I would guess the average age of the other travellers was about 80 years. There were drinks and snacks available on board and I was genuinely shocked at the amount of alcohol that was consumed - morning, noon and night. During the day almost every hot drink (including soup) was requested to be served with a shot of booze and most frequently they were doubles, then at the evening meal in the hotel huge amounts of alcohol were consumed. So, not particularly age related then.
