Sixty thousand miles long. That’s the length of the tube system inside us that transports blood, oxygen, and nutrients to the cells throughout our bodies.

If these tubes fail, the result can be fatal. In some cases, it’s a heart attack. In others, it’s a stroke, when the blood supply to the brain is disrupted and brain cells are damaged or killed.

Heart attacks and strokes are a major cause of death in developed countries — but we can take action to reduce the risks.

In this episode, Jonathan talks with a world-renowned physician, scientist, and speaker to gain insights into how looking after this magical pipework could slow aging.

Dr. William Li is a world-leading specialist in blood vessels and preventative health, and the author of countless papers on the topic. He possesses the gift for communicating about this complex subject in terms we can all understand.
