once I hit 40, I noticed that I became far more receptive to giving and receiving advice.

I used to think old people gave advice because they were know-it-alls, but now I think it’s just because it can take a while to really understand that experience is valuable

That wasn’t my experience at all. Most people who gave me advice unsolicited gave me bad advice, while those I sought out were hesitant to steer me, but what they did provide, was quite valuable.

You likely get a lot of unsolicited advice you don't recognize as such. Be kind to people, look both ways before crossing the street, be honest, eat healthier, workout more, etc...

That’s mixing together a broad set of things I wouldn’t consider aa advice, so much as basic socialization. Potty training toddlers is not giving them advice.
