Large Age gaps

hi there, have you experienced an age gap relationship in your life? to explain this context of 'age gap' i'm talking 30+ years between two people, different generations of people.. i'm focusing on parental age gaps and the differences in everything really.

my biological parents have a 40 year age difference; father from the silent generation and mother from late generation x/early millennial and i have my own experience of what this impacted and affected my childhood but i want to hear from anyone who might have experiences something similar?
