8 Mind-Blowing Bits Of Sci-Fi Tech That You Will Live To See

6. Eternal Youth

Don't get too excited, but we might be about to crack the whole "ageing" thing. The theory goes that the reason why you're starting to see wrinkles, hear creaky joints and get a little bit fatter every day, is because your body is accumulating molecular damage as it renews and repairs itself. As cells are copied and replaced, some of them are copied poorly, and this damage accumulates over time, causing your body to degenerate. But, what if you could, I don't know, regenerate? Well, some scientists reckon they're on the brink of being able to slow, stop and even reverse the ageing process through gene and stem cell therapy. This isn't just to give you the dewy complexion of a 16-year-old in the twilight of your 40s, but it could be the key to tackling all sorts of degenerative diseases like Alzheimers and even cancers. And, yunno, making sure you're still a total slice when you're 70.
