Why would my hand eye coordination improve in my early twenties and continue til now?

When I was younger I could never get the basketball inside the basket when I was in the gym but as a 23 year old, I was just as good as anybody else at getting the basketball in the basket and now in my 30s I’m able to control what part of a bucket I want to target when I throw used toys into my plastic basket for kids who come over for social activities. This means that in my 30s, my coordination is better then what it was in my 20s.

Why would my hand eye coordination improve in my early twenties and continue til now?
