I just got this in my head and thought it would be interesting for others to figure out too. Math is the one thing in the Universe that ties everything together - the only thing that keeps us from understanding EVERYTHING is just an equation or two away!!!
So here is something to ponder...
When I was 10 my Mother was 30, she was 3 times my age (or if you prefer, I was 1/3rd her age) and when I was 20 , she was 40, I was half her age (she was twice as old as me) and when I was 40, she was 60 - I then was 2/3rds her age, she then was only 1/3rd older than me.
My point, I know I'll never catch up EVEN if we lived forever, but At what age would she only be 10% older than me - or for you left-brainers, at which point would I be 90% of her age?
So, when will I get to 10% of her age, it might me MUCH OLDER than you'd think, it seems the older we get, the more the percentages slow down - good luck!!!
