You get to where I am, 20+ years in the business, it is hard to remember them all. I can of course remember my first professional experience. Don't know how many in total over my lifetime, I estimate 350-450.
It is true I think back to encounters over the last year (and I keep a small data base of names but not photos or descriptions of service) and some of the names I seriously cannot recollect any thing about them Those that were good I went to see 2 or 3 times (and of course my 141 regulars, who are here for more than a few months, and whom I have visited regularly during that time) I can recollect. Others, one offs, are just names on the paper, I have no idea about them, only that I saw them, paid them $, and forgot all about any other details. Pretty scary in some ways.
My brain only holds the info that it thinks is relevant. Like RAM, the old data gets pushed out by the new incoming data.
Have fun, be safe
