If you were magically 16 again, that would mean that your memories would only be 16 years old as well. You can’t go back and fix the stupid shit you did as a teenager because you wouldn’t remember…but you might possibly make new stupid mistakes.
So…who amongst us wants to go back to that age of angst, insecurity and hormonal upsets?
Without any new wisdom gained, I’d likely make the exact same decisions I did back then, so no.
The only reason I’d want to go back to being sixteen would be to change things I fucked up, so no. (Well, that and the music. Music was better in the 90s.)
Hell no. Once was enough and I might not do as well a second time around.
Hard to imagine I’d do worse. I think I’ll take the deal!
Fuck no!
Let’s see. At 16 I was in charge of two depressed, one bedridden parent, and two boys too young to be much help. They were old enough to prepare the table and straighten their beds, not old enough to buy anything more complicated than bologna and couldn’t be trusted to prepare their own afternoon snack, as they would have used normal amounts of bread and whole-month’s-worth of filling.
I’m sorry, why would I want to go back to that particular year? I already survived it once!
Hmm. Would I know it was a repeat? If I knew it was a do-over (I liked that show, btw) but didn’t know why, yeah, I’d go back. Just knowing it was a repeat would have me considering things more carefully. Though it might drive me crazy wondering “Wait - did I do this last time?” 
Laughs with you. Yes, I agree that the music was better back when I was that age…but I understand that we imprinted on it during our time of angst and playing MY/OUR song over and over.
It was hell for me. Pass.
Can I just have my sixteen year old body back? I promise I’ll take better care of it this time.
I wouldn’t mind it. I liked my teenaged years. I like my life now, too, so for the purposes of the OP, I’d say no, but I had a good time at that age, so either way works for me.
if i don’t remember, then this current me would be dead and gone if i go back.
Knowing no better than I did then? No way in hell!
If you mean 16 now, in 2014, absolutely:
Good chance of living to 2080, and beyond. Instead of growing up waiting for tape-based games to load (then trying to figure out what the burger-like thing I’m controlling is supposed to be) we begin with…whatever generation current tech is supposed to be.
And it’s no problem moving to a new town and finding social events now…was pretty tough when I was in my early twenties.
If you mean back in time to when I was originally 16, still yes:
I fucked up my teens so bad I have nothing to lose from rolling the dice again (I assume we’re re-rolling, not just repeating everything).
It wouldn’t be me if I don’t remember, so I don’t see the point.
Pretty much this. I mean, flip a coin. I’ve had some shitty years in between but I got where I am, in large part, due to mistakes I made.
If I had the chance to do it over with the knowledge I have today, sign me up. If I don’t remember anything, I’ll probably make the same stupid mistakes and may not get as lucky next time. Ask me the same question on any particular day in my future and the answer might change, but today the answer is “no thanks.”
Not to be overly dramatic, but how would this significantly differ from suicide, from a personal perspective?
Another vote for this position. It’s just a fancy form of suicide.
Wow, three in a row fighting the hypothetical.
I assume that the OP is saying it is the same instance of consciousness. Which, yes, is problematic to define, but hardly a problem unique to this hypothetical. We have to make certain assumptions about identity every time we talk about our past and future.
One word: premature ejaculation.
No. Losing the memories of everything I’ve learned and done, that’s the same as dying and being reincarnated as my 16 year old self.
If that’s an option when I actually die, I’ll take it but I aint going to volunteer to go now.
