Let me try and make this simple for you. Do you think the quality of life has considerably improved from what was there around 1000 years ago. A simple yes or no answer. Dont beat around the bush.
I sincerely believe that the quality of life has considerably improved. This has happened because of some of the path breaking discoveries and inventions. It is easy to sit in an armchair,watch the TV, talk on a cellphone and then blame scientific advances for all the ills of society.
