Does turning 21 make you less inclined to drink?

Title might seem like a weird question (because i feel like you think it would make you more inclined to drink if anything) but I swear this happened to me. For context, not an alcoholic, but I’d say since I was 17 or so I’d probably drink a couple times a week usually with friends but sometimes before bed or while watching a game or movie or something, (just to make clear this is not a post about whether you think I’m an alcoholic or not) anyways since I turned 21 I’ve barely drank, like when I first turned 21 maybe the first week I was buying drinks mainly because it felt good to be able to buy without fear of getting ID etc (because I could lol) and pretty much since then I have drank twice in the past 4-5 months. Literally no desire to drink what so ever, in fact when I do think about alcohol its mainly about the fact that I have no interest in alcohol anymore lol. I do plan on drinking at some point in the future, not like I made a vow to go sober or anything, but literally 0 interest its wild. Anyways is it because I literally just outgrew that phase of my life? Or is it because theres no longer “a rebellious” feeling that I get from doing it now that its legal for me? Before I never thought that that could be the case but I’m really starting to think it could be that, what do you guys think?
