Personalized medicine starts with a question most doctors never ask you. Len May has built his life around it. On this episode of New Normal Big Life, the EndoDNA CEO argues that the system we call healthcare is really sick care. Moreover, he believes that the map out of a broken system is already written inside you.
Sick Care Vs Healthcare: The Personalized Medicine Shift
Len does not mince words about why most of us only see a doctor when we are already sick. He frames your genetics as the GPS of life, the thing that shows you where the potholes are before you hit them. Furthermore, the conversation reveals just how medicine can be personalized when responsibility for your health outcomes shifts to you. Additionally, what he says about who holds responsibility for your outcomes is going to land differently than you expect.
Epigenetics: The Switches You Control

Here is the idea that reframes everything. Len says only 20 to 30 percent of your genes are switched on when you are born. Three forces flip the rest. These are what you eat, what you are exposed to, and something most people never factor in. He names the third one in the episode. Importantly, it is the one you have the most power over. Len explores how personalized medicine highlights the influence of lifestyle choices on genetic expression.
The Endocannabinoid System And Why Dosing Is Personalized Medicine
Len debunks three things most people accept as fact about cannabis, starting with whether it is addictive at all. He walks through the endocannabinoid system in detail, your body's built-in balancing act, and a disarming tequila analogy that flips the addiction blame in the whole debate. The takeaway is bigger than cannabis. In this discussion, the importance of medicine tailored to the individual—personalized—emerges as critical to understanding our health. Your right dose of anything is yours alone, Len says.
AI In Medicine And The Future Of EndoDNA
Len reveals how his BIOS platform pairs your DNA with AI in medicine to hand your doctor a personalized protocol. It then learns from your results to sharpen its recommendations. In the future, personalized approaches to medicine could revolutionize prevention and treatment. Where this is headed for prevention is the part that stopped me cold.
