50-year-you has lots of experience in the domain of 'you' and knows the future (via your lens) from when you were 20. 50-year-olds when you're 20 will lack those things. Also, everyone has holes in their knowledge/perspective. Could be the older people in your orbit when younger have thoughts that are too limiting compared to where you end up when making decisions as a 20-year-old.
