At what age would we consider the smaller, thinner models?

Question for this group of people who share a common interest--
As we grow older, at what age might you consider the smaller, thinner models?

I have a chunky Deepsea and a Planet Ocean in addition to other pieces. I did wonder at what age I may think to consider the Datejusts, Day Dates, older Aqua Terras, thinner JLCs, etc. as I grow older.

Obviously, those with 7.5 to 8" wrists may have a different story. As I *could* be an AARP card-carrying member (I'm not) I wonder at what age I stop wearing the chunky models and look at the thinner, lighter models.

Just throwing it out there for the group.
