Can aging be slowed down or reversed?

Yes, it is possible to delay aging. It has been shown that it is possible to reverse the aging process in some scientific experiments with human cells and simple organisms. However, it is not yet possible to reverse aging in humans, despite the publicity hype about blood transfusions to young people in Silicon Valley. In an experimental study, researchers combined the circulatory systems of old mice with young mice to see what would happen and discovered that the young mouse began to age while the old mouse grew younger, as their old and young blood mixed.

An example is the TAME (Targeting Aging with Metformin) trial, which aims to find out if the antidiabetic drug metformin can delay aging and reduce the risk of many aging-related diseases at the same time (R). Unlike your chronological age (how many birthdays you have marked), your biological age shows how well your body withstands the ravages of time and how you compare yourself to other people who have lived the same number of years. For example, the immune system rejects stem cells (this is the case of “allogeneic stem cells that come from other people”) or they are already aged and damaged (this is the case of autologous stem cells, which come from your own aging body). There are many proven ways you can help increase your life expectancy if you stay healthy well into old age, even if that doesn't necessarily mean reversing your biological age.

Various biotechnology companies and research groups are trying to identify rejuvenating substances in young blood, with the aim of administering them to humans to improve health and delay or even partially reverse aging (R). Treating aging would allow for much more effective and better treatments to prevent, delay, or even reverse aging-related diseases.
