Dear Sir, You will ask Ibn Sina the medical scientist a question when met. What to do to keep the body healthy. A very good question. You mention three wonderful discoveries. Transportation, medicine and technology and telecommunications are three inventions that have improved who we are. Without science, we would have hunted and eaten animals like primitive people. Stone had to be rubbed against stone to start a fire. But medical science has made our life much easier. Vaccines have been invented to protect against epidemics over the ages. Your writing about science is very beautiful. Good luck to you.
