My brother who is a doctor can't figure out how I'm able to travel the world so often - having traveled to some 128 countries in all 7 continents. Even visited Esperanza Base in Antarctica where not many frequent travelers visit. Flew to Mt Everest, dipped my feet in the Dead Sea, visited both the southernmost and northernmost cities of the world. Also traveled the Silk Road route that included the countries of Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan where not many have traveled. Have friends in many countries including Russia, Germany, France, England, Canada, Mexico, Singapore, many cities in the US, and Cuba. Have met many interesting people during my travels including Bob Brodsky the rocket scientist who taught Astronautics at USC and Iowa State University. We kept in touch for many years until he passed away last year. That's quite a feat, if I say so myself.
