It's mostly nonsense. Some parents are straight up bad, yes, but usually because they're ****ed up people so they won't really regret it. The rest, who do have regrets, fall into two separate categories.
1) People who think they could have done differently but, realistically, couldn't either due to circumstance or just who they are as people.
2) People who could have done things differently, but would probably
still have regrets, just different ones... because there is no such thing as "perfect".
I doubt this statistic means that 29% thinks they got it spot on. Most probably just accept that "life happens" and there's not much point in having regrets / wishing to change the past... because all you end up with is things being
different, not necessarily
better. People who don't realise that need to watch The Flash or Back to the Future
