Aging is been scientifically studied over a century now by Biogerontolgists. They have defined seven basic causes for aging during that time. The last reason for aging was found in 1981, and no other reason is been discovered after that. In perspective of anti-aging research, it is now been argued that if therapies could be devised to take away the toxic outcome related to each of the aging causes, then the lifespan could be certainly be expanded indefinitely.



Following are the seven primary causes for aging listed by well-known biogerontologist:

Cell loss

Nuclear Mutations and Epimutations

Mitochondrial mutations

Cellular Senescence

Extra cellular cross-links

Extra cellular junk and

Intracellular junk

More research is happening to locate the solutions for such biochemical issues. As you grow older with time, muscular atrophy sets in half because of reduced levels of hormones and growth factors. Injecting expansion factors or cheering exercise might to an extent improve this, even though a long-term solution would certainly need the use of stem cell therapy. Due to a range of causes, the hereditary substance in the nucleus of our cells intermittently changes, even though this reason of aging is kept in hand by the huge redundancy of the cells in body system. Nuclear changes are only really dangerous when they generate cancer cells that could duplicate and overtake the entire body.

The control plants of our cells are mitochondria, organelles that generate ATP, the energy level of all life. Just like our nucleus of cells, mitochondria also have some of their own inherited matter that is actually vulnerable to change. Mutated mitochondria might get out of control and root serious oxidation harm to tissues of our body system.  There are lot types of intracellular and additional cellular junk, which is upsurge in the body, one case being the amyloid plaque located in Alzheimer's patients. To offset such reason of aging, researchers propose finding enzymes able of breaking down the criminal molecules with no damaging nearby tissue.

The final two major causes of aging are cell senescence and extra cellular crosslink's. When it comes to cell senescence, cells do not die when they're actually supposed to. In its place, they bond around, taking up room and exuding possible dangerous proteins. These are known as death-resistant cells.  Extra cellular crosslink's are only what causes an elder person's skin to turn out to be rough and with wrinkled. Cells are usually held jointly by protein cross linkages, but these could become too opaque and lead to lot of health problems. The future solution is to find multiple (called AGE-breakers) that crumble the surplus crosslink's.

If all the reasons of aging could be sorted out using biotechnological solutions, then human beings might be capable to live for thousands of years - provided they do not die from not natural means.
