Key #7: Go High-Tech
There’s no magic bullet for us yet, but our grandchildren may be around a lot longer, thanks to these high-tech life lengtheners in the works:
- Replacement parts. Increasingly available man-made parts, from knees to brain implants, may be even better than our originals. And scientists are using adult stem cells to replace aging tissue, so you could strengthen a weak immune system, regrow heart muscle after a heart attack or even undo paralysis.
- Nano-healing. Tiny devices could go inside our bodies and fix or remove blood clots and damaged or precancerous cells.
- Better DNA. Our chromosomes are capped with telomeres (like the plastic cap on a shoelace). Each time a cell divides, its chromosomes do, too, and telomeres shorten. When they get too short, the cell dies or becomes vulnerable to disease. The answer to a longer life, then, may be lengthening our telomeres with diet, exercise or drugs.
