The human race has won much in the struggle against age and age and death. The average life-span of a man fifty years ago would be but forty or fifty; but now we see men, seventy and eighty years old, as vigorous as ever.
In the 1980s, scientists were able to make humans produce insulin by inserting human genes into bacteria. This helped start the first boom of DNA recombination and bio-technological drugs. Nowadays, with tools like CRISPR and gene circuits that are more precise and complex, we can program biology in a way never possible before. For example, we can engineer bacteria to produce new chemicals or proteins; or use cells to attack cancer cells. The explosive growth of “programmable drugs” (in the form of genes, cells, microbes) is now making us closer than ever before to what might be medicine’s Holy Grail—curing age-related ills including aging itself.
People say “if it’s possible in science, it’s also possible in engineering.” This is often applied to biology.
You cannot stay young forever. It is only because of medical advances that you can repair and reverse the aging process – damage to your body. To maintain youth, you can rely on external treatments and longevity pills. This counts as achieving immortality if we can eventually edit DNA from a genetic level, so that the person’s body repairs itself, DNA and proteins. Then this would be truly immortalized forever!
Today we still cannot do anything
Control your food intake, do exercise, and treat the diseases of old age to help extend life. But it is not enough.
But tomorrow’s technology will have a way to solve the problem. It might be much faster than you imagined.
The life span is controlled by our genes. Genes are things that you can change. Today, gene treatments are used to treat many genetic diseases. Tomorrow, there will be gene treatments for aging because aging is also a genetic disease in its essence.
Only one thing is sensible. That’s cryonics. We hope for future advances in biology and medicine.
