Age robs us of the ability to choose areas to become expert it. It's still possible, but so much harder, and we are so much more aware of the opportunity costs.
@Flux Nah. Our slightly diminished capacity to just study bullshit for endless hours is more than made up for by our accumulated knowledge of which bits are a waste of time.
@TomF only in areas we already have collateral in. 10 years in I play guitar almost as well as a 16 year old who cares.
@Flux Oh well sure - I started playing keyboards a few months ago and I still suck. I've been racing cars for 5 years and my progress is glacial compared to an 8-year-old in a gokart. You have to leverage your synergies!
