I would, with mine.
My timeline is:
Born in ‘89 Toddler/Child in 90s Teenager in 00s’ Young Adult in '10s Adult late '10s to present.
I’d want mine altered so that it’d be:
Born in ‘70 Toddler/Child in 70s Teenager in 80s Young Adult in 90s Adult in 00s’
And by now I’d probably be closing in on my 50s.
You are describing me. :)
And yeah, I’m happy with my timeline. If anything, I would move it back even more. Born in the 60s would open up for a lot of cool stuff in the 70s.
