Those wacky scientists are at it again. And if they have their way, we’ll live a very, very long time.
The latest? Scientists have perfected a technique where they lengthen the telomeres of cells’ chromosomes. The length of telomeres, which protect cells from damage, corresponds with the health of cells. The longer the telomeres, the healthier the cell. By artificially lengthening the telomeres, they’ve turned back the clock on these cells. OR, to put it another way, they replenished the cells’ bank accounts.
Before anyone books that vacation a hundred years out, this has only been done in the lab, on cells. The scientists believe that this technique may someday help treat diseases of aging such as heart disease. So, it seems that everlasting life would be a piecemeal thing — treat each condition as it comes up.
But there’s always the dark side. If we lived forever, or close to it, where would we all fit? We’d definitely have to colonize Mars, and Venus too. And what if it goes wrong? What if the procedure turns us into a race of zombies, as in Resident Evil? Now that would make life interesting.
