3/4 looks like 50's, rest looks 60's or in pension.
Quite a few looks like probably smoking and then face smoothing by the AI.
Wonder what my one will look like, actually question is more like where, since ~7/56 are still in South Africa if you include those who are "only" South African. Right now, Stuttgart looks popular, not sure why, but around 5 are there (also recently got an offer there for ~70k EUR gross a year, was tempted, may be why, or because lots of unis there), second is probably Vienna at 3 (all of Austria at 5), maybe LA there are 3 there as well.
Most aren't really on FB anymore either, platform is pretty dead among my age group, you get someone random post something once in a while. Used to be on for memes since friend posted them every second day or so, now he rarely does, very sad. Wonder if it's just because people can't do things during pandemic/people actually started finishing studies and have to work, no more uni life posting lol.
