When you grow older, you get wrinkles, gray hair, and your bones get weak. Most people just think it's because your body just gets old and weak, but that isn't the case. The mitochondria that's in every cell in your body becomes mutated, which makes you grow gray hair and get wrinkles. Nils-Göran Larsson of Karolinska University Hospital in Sweden recently ran some tests on a couple of lab mice to have their mtDNA mutations develop faster than normal. These rodents suffered age-related conditions such as hair loss, osteoporosis, anemia, and infertility much sooner than your typical mouse, and they died a lot younger as well. Now some scientists are looking for ways to try and find a way to slow down or stop these mutations from happening.
This is an interesting story for me because I never really understood why people got gray hair or wrinkles. I had always thought it was just because they were old, but that wasn't right. It's funny, in a way, that you get gray hair and wrinkles because your mitochondria in your cells get mutated. I really hope that they find a way to either slow down or stop this mutation from happening because I personally do not want to have gray hair or wrinkles, especially the wrinkles.
