People over 110 years old share unusually robust immune systems with high levels of cytotoxic T cells. They tend to use probiotics, do high intensity interval training, and take medicinal mushrooms. These habits may explain why some people live so much longer than others.
So there was a fascinating paper that caught my eye looking at what is it about super centarians that makes them so healthy and what makes them live so long? And a super centarian is defined as someone who's over 110. So by definition, if you live to 110, you've got to be pretty tough. Okay. And what they found is that the super centarians had higher levels of the cd4. cytotoxic T cells. And these are some of the natural killer immune cells. And what we see is that these cells are the cells that allow our body to fight off infections and to fight off viruses. So having a robust immune system is critical for having a healthy lifespan, a long lifespan, and a health span. And the things that play a role in improving your natural killer cell functions are things like probiotics. things like high intensity interval training, things also like medicinal mushrooms and feeding the gut microbiome. So these are all things which are really, really key to keeping a robust and healthy immune response so that you can fight off things that you may encounter.
