I just saw this tweet from Paris Hilton.
It reminded me of when I was a little girl (5-7 years old), and adults would say: "I wish I could learn X (piano / foreign language / math) but I am too old now and cannot learn as fast as I used to."
I became very afraid of this aging process that would rob me of my memory and capacity to learn.
Well, now I am close to the age of those adults when they said this, and it was not true at all! It was all nonsense. If anything, I am better now at learning, because I know how to mix breadth and depth, and when to read a book vs practice the activity hands-on vs watch a lecture on the subject.
My memory is only worse in that I sometimes have interference. I used to scan a file of code and rely that I could remember all the variable names and constants. Now I get confused between the code I just scanned vs code I scanned in the past, so it is a bit harder if I just do it offhandedly. But if I concentrate, my memory is just as good as before.
I also remember being on a recruiting trip for Google in China, and a young female student asking me with sincerity, "We all know women's memories become a lot worse at age 30, so should I still go into programming, knowing that I'll be unable to keep up with new technologies in a decade?" I was outraged at the time, but I was not yet 30, so I could not completely debunk it. Now I am over 30 and can definitively say that was hogwash!
Women have also told me that their memories got worse after having a child. I have not had one yet, but when I do, I'll be sure to update and reject that one too.
All that fear-mongering for nothing! Why do we do this to ourselves?
