Stem Cell Exhaustion: As we age, our supply of stem cells plummets, in certain cases by a ten thousandfold decline. Worse, the ones we do manage to hang on to become far less active. This means that the body's internal tissue and organ repair system loses its ability to do its job.

Thousands of years ago, it was only kings, pharaohs, and emperors who had the ability to solve large-scale problems. Hundreds of years ago, this power expanded to the industrialists who built our transportation systems and financial institutions. But today, the ability to solve such problems has been thoroughly democratized. Right now, and for the first time ever, a passionate and committed individual has access to the technology, minds, and capital required to take on any challenge. Even better, that individual has good reason to take on such challenges. As we will soon see, the world’s biggest problems are now the world’s biggest business opportunities. This means, for exponential entrepreneurs, finding a significant challenge is a meaningful road to wealth. Ultimately, as I teach at Singularity University (much more on this later), the best way to become a billionaire is to solve a billion-person problem.
