Biologist David Sinclair addresses these concerns in his book Lifespan, coming to the conclusion that humanity has got what it takes to overcome them. Keep reading to learn about the implications of human immortality, according to David Sinclair.
What is the human gut microbiome? How does it influence our physical and mental health? We have huge populations of bacteria in the human gut microbiome. These bacteria play a vital role in digestion, and emerging science suggests that they also have other important effects. These include strengthening our immune system and possibly impacting our mental health. Keep reading to learn about the role of these bacteria populations, how we develop them, and how we can maintain a healthy gut.
What is David Sinclair’s Lifespan about? What is the key message to take away from the book? In Lifespan, David Sinclair discusses why aging happens, how we can prevent it, and how we might create a world where nobody has to die of old age.

Is the appendix useless? What is the purpose of the appendix? The appendix has a reputation of having no practical purpose in the body, but that’s not true. The appendix is a vital part of the digestive system; it kills bad bacteria and maintains good bacteria. Learn why the appendix isn’t so useless after all, according to scientist Giulia Enders.
What is the gut? What function does the gut serve in the body? Your gastrointestinal tract starts in the mouth and ends at the anus. The gut serves a number of important functions in the body, including breaking down food into its constituent nutrients, regulating the microbiome, and eliminating waste. Here’s how your gut works and why it’s important to keep it healthy.
