Jet life till my next life
With all the immature ish you post on here, I'm shocked you're 27 tbh.
But to answer your question, no, it's not too late to get married- esp since you're male. 30 to 35 is the best time for men to get married ( esp. if they're not particularly religious, and don't mind being an older parent/or not having kids).
Oh hell nah. I want my kids to know their grandparents, I want them to bond with my parents. There's that joy seeing your kids with your parents
