There is a “class” concept by Pierre Bourdieu, that in short says: everyone belongs into social fields (~ classes) depending on their economic, cultural, and social capital and every field brings a certain set of what I would in short call socially accepted behaviour - his term is habitus. It is possible to move from one social field to another but it comes with cost. For example, moving upwards in society because one gains a lot of money, might get this person into a “higher” field. But their habitus might not change because that requires the person to learn the new acceptable behaviour. The person can learn, but because it doesn’t come naturally you could probably see their struggle maintaining the ne habitus. Therefore you can determine from their behaviour/looks, if they’re nouveau rich etc…

My description of Bourdieu’s concept is probably very flawed, sorry about that!

Apart from that, I think, less moving faces could have resulted from using anti aging products.

I’m finally starting to get my sense of smelling back AND went to see alpacas.

There are languages that use words or particles of words to indicate a question, for example Turkish and chinese languages.
