One way to look at our path to longevity is to regard it as a journey over three sequential bridges. Bridge One is based on therapies that exist today. Bridge One therapies consist of the best of present-day medicine, including biotechnology breakthroughs that are occurring every day. Bridge One will take us to Bridge Two, which consists of the full blossoming of the biotechnology revolution. Then Bridge Two will take us to Bridge Three, the nanotechnology/artificial intelligence revolution, which will lead to life spans that are currently incomprehensible, but which will soon be commonplace, measuring in the hundreds of years.
There are several Bridge One technologies that people can do themselves without the aid of medical professionals. These include things like proper diet, caloric restriction, adequate exercise, stress management, aggressive nutritional supplementation, detoxification and proper care of your brain.
There are also things that can be done with the help of medical professionals. For example, you can have your genomics tested; you can have tests done to determine specifics of your metabolism such as methylation, inflammation and glycation defects. You can undergo testing to detect heart disease early and then take measures before it has a chance to strike. You can detect and prevent cancer before it has a chance to spread. You can avail yourself of bio identical hormone replacement therapies.
