Mans Heart Health

At the age of 28, with his Beijing-based science communications business doing well and a new relationship blossoming, Ben Bravery woke from a colonoscopy to be told he had stage 3 colorectal cancer. As a scientist, Ben understood the seriousness of his condition. Cancer had quite literally whacked him in the guts, after all.

And what does it really feel like to touch your own heart, or to have someone else's beating inside your chest?
