How to Cure Aging – During Your Lifetime?
Health is the most valuable thing people have in life. Often people don't realize that until they or someone they know gets ill. People might take their health and their looks for granted until they get older and their health begins to deteriorate and their skin begins to age. The good news is that there are things that people can do to help cure aging. These days people are living longer lives than ever before. But because people are living longer, that also means that people might spend a larger portion of their lives being sick. Getting old might also mean spending more time living in pain. So scientists are trying to shift the attention of the medical community from optimizing lifespans to optimizing health spans. Which is the part of peoples lives where they are living healthy and disease free. There are several ways to do this. To start people need to attack the root cause of almost all bodily defects that affect aging itself. Unbeknown to most people the science of aging has made a lot of progress in the last few years. With human trials about to begin shortly. The following discoveries might affect people who are alive right now. While most people think that living healthy, positive life tips and organic foods are the way to a long and healthy life; scientists are finding other ways.

Senescent cells. The cells in your body have an expiration date. Each time one of the cells in your body divides, it copies its chromosomes. Because of the way this works, they lose a tiny bit of DNA at the ends. The result could be catastrophic, so to protect themselves they have long segments of DNA called telomeres, that are a bit like the stiff ends of shoe laces. They shrink with every cell division. In some cells after some divisions, the telomeres are gone, and the cell becomes a zombie, otherwise known as a senescent cell. Senescent cells stay around and don't die. The older you get, the more of these senescent cells there is inside you. These cells harm tissue around them and are linked to many diseases that accompany old age, such as diabetes and kidney failure. But what if you could kill these cells off? Scientists have genetically engineered mice so that they could destroy their senescent cells as they pleased. Older mice without the senescent cells were more active, their hearts and kidneys worked better, and they were less prone to cancer. Overall these mice lived up to 30 percent longer and were in better health than average mice.
Since all the cells in the human body can't be genetically modified, scientists need to find another way to get rid of the senescent cells. The question is, how do you kill them without harming healthy cells? Most cells in the body commit a programmed cell suicide when cells are damaged, but senescent cells don't. It turns out that they underproduce a protein that tells them when it's time to die. A 2016 study gave mice an injection of this protein, and it killed 80 percent of their senescent cells while causing almost no damage to their healthy cells.

You will find this video on the Kurzgesagt – In a Nutshell YouTube channel. On the site, you will find videos that explain things with optimistic nihilism. You will find a variety of videos with everything from living healthy, positive life tips and more. They are a small team who want to make science look beautiful because they believe that science is beautiful. Currently, the site makes one animation video per month. **
