I would love to see data on the age they decided to master a given field. For instance if you decide to master programming (w.e that means) and it takes roughly 10 years to achieve mastery then you should expect a great accomplishment 10 years after you've started diving deep in a field. My assumption that it's rarer for those who are older is probably due to the fact that they have to worry about making a living and there aren't as many resources where you can engage with your peers outside of university, and also the fact that as a kid, making mistakes is not frowned upon but merely a process of discovery, whereas when you're older there is a lot of negative emotions associated with failure.
