Quantum Leap

Ok, this is a totally abstract concept, and I know similar scenarios have been debated before, but this caught my imagination enough for me to post about it here. anyone who has seen Quantum Leap will be familiar with the idea of your consciousness time travelling and jumping into someone else's body, and I think there may have even been an episode of the show where something like this happened, but I want you to imagine what it would be like to quantum leap into yourself as a teenager. This is obviously way out there, but how do you think you would be able to cope with that, on the surface it sounds great, getting to live through it all again but with all the knowledge and skills you've developed since then, it sounds like a doddle, then again, maybe not.
In the years since you were a teenager you've grown up psychologically, and the events you experienced since then have formed your persona, what kind of impact would this have on your behaviour if one day you woke up to find yourself back as 15 year old again? What would be your initial impulses? What things would you want to go and do? What would be the first thing you try to change about your past? Would you even want to change anything about your past when you consider that the events that occurred are what have made you the person you are? If you felt the need to change events, would that mean that you are not happy with who you are or would there be other reasons for changing events?
I think some of the factors that I would find most difficult would be the way people would treat me, I was a very different person at that age, so to suddenly find myself back in that time, place and body but with the mind I have today, it would be one hell of a shock to the system. I also had a very different opinion of a lot of people back then to what I do now, as well as a very different attitude and outlook on the world, so as far as other people would be concerned, my behaviour would take a very sudden and dramatic turn, and I imagine that behaviour would not suit a 15 year old for the most part. Of course, it's also entirely possible that you would start to think and act like you did at that age the first time around, all the influences around you would be pushing you to adopt the thoughts and behaviour expected of you, and also there would be some many associations that might cause you to regress.
I'm not really getting at anything with this post, I just found it an interesting debate topic and I'd like to know what other people think would happen.

Heroes: Time Travel for Idiots

Season 4 of Heroes, the X-Men for the 'I'm not a geek' geeks, has just started it's run in the US, and watching the first episode I once again find myself wondering 'why do I watch this tosh?'
The answer is simple really, I like action, especially when that action is centred around various superpowers that help me indulge in my fantasies of what I would do if I had some amazing super ability of my own, which is why I quite enjoyed the film 'Jumper'. Actually, there was one other thing about Jumper that I liked, and a similar attraction also exists in Heroes in the form of Claire, oh man, how I would like to wreck that chick...
But back to the topic at hand, we find ourselves with yet another set of plot inconsistencies, which it seems the writers of Heroes are now throwing in as a social experiment to see how long it takes before everyone has given up on watching the show bar the most gibbering of idiots... (yet I'm still going to carry on watching, less said about that the better). What really gets my goat is all the time travel plot lines, I have nothing against time travel as a plot device, as long as it's done right, but seemingly every time Hiro jumps into the past, something happens that clearly would have had a knock on effect that would have altered everything we have seen so far. This time around, Hiro verbally expresses this, only to have the writers go so far as to have another character tell him that it's OK to change 'just one thing' without altering all of the past... resulting in Hiro changing 'just one thing' that anyone who remembers the events of season 1 and has just a shred of intelligence would realise that it would have completely altered most of the events we have seen anyway (namely it would have meant Ando would never have sought out Nikki in Las Vegas, and the knock on effect from there). what the writers have tried to do is make this 'one thing' that Hiro changes different from what he originally intended to change, thus an attempt at misdirecting the audience was made, and it fell flat on it's face.... again.
Personally, I find this kind of thing insulting as a viewer, it's as if the production team don't believe their viewers have the intelligence to realise these things... either that or they don't have the intelligence to write a coherent story, but then who's more the fool; the fool or the fool who follows him?
... but it does have some entertaining (enough) action sequences, albeit brief as they are, and the corruptible looking Hayden Panettiere... so I guess I am committing another 23 hours of my life to this over the next 6 months
