So, scientists have recently discovered that by removing a part of the DNA that causes itself to self destruct over time, they can make organisms live at least 100 times longer than expected. If you could live forever, what would you do?
If it was proven safe and tried out, I'd go for it. I mean, there's no history of dementia/Alzheimer's in my family, and if they have this, odds are they'll be able to cure the severe arthritis that I'm bound to get. I'd totally try it out, try to learn as much as I could, and use it to develop even more medicines, cures, and inventions.
This would wreak havoc on the world's population, though. Unless we colonize other planets (which may be possible by the time this technology is developed and approved and used and stuff) we'd be totally screwed.
