When I was 28 years old, found I had high blood pressure. Over next 7 years I took BP meds but also lost weight and worked out. Doctors ran tests but never found a root cause - it was just high for no assignable reason and I was told to take meds. At 34 years old, was in best shape of my life, except still taking BP meds. That year, I stopped taking the meds, but monitored BP every few months. It was borderline high but not crazy.

So this year, I turned 38, off the BP meds more than 3 years now. Then, last month while in China with my family, I had a full blown stroke. Result was lost 2cm of my left brain directly in the region that controls speech and right arm & hand motor skills. Spent 8 days in a Chinese hospital.

For about one week, I talked like a stone cold drunk and my right arm was useless. I thought I might be that way forever. Luckily, after two months, I'm basically fully functionally recovered. Bottom line is the path from a risk indicator like high blood pressure to a stroke or heart attack can be fairly short. Now, at 38 I know I must make some radical change if I'm going to live to 70, no less not be a paralyzed half brain dead invalid.

I'm certainly interested in quantified self tech now. The problem is everyone that needs a doctor to take an intense personal interest in their long term health cannot possibly find a doctor to do so, for any number of reasons. Opportunity is to empower the individual non-medial experts to easily monitor their own health and risk factors over time. Will likely be moving into product development in this space myself.
