Humanity health The Health of Humans

I had one interesting discussion yesterday. It was about health, global humanity health. My friend said that in our time, peoples are now more healthy than years ago. He reinforced his opinion by stating fact: Today medicine is so full of innovation that and not stay most illnesses have no chance. Modern doctors have the latest hi-techs gear/equipment and science achievements on duty (I don't understand what your're trying to say). Now we can cure illnesses which caused were death years ago. We cat can't cure all every disease, but most of them diseases.
I disagree with his position. I'm thinking I think that we have more global problems with health than years ago. Obesity, diabetes, heart diseases were never at such so shocking rates scales. In our days Right now, we can read about new viruses every month. Why then, in spite of we us having such strong and innovative medicinal techniques do we stay ill? I see only three reasons for this it. At first: We have live a wrong lifestyle. We eat too much sugar and move too little. Though, there's Good news that, everybody who wants to, can correct it.
Second problem is our polluted environment. We waste gases and water,along with different accidents on industrial enterprises which aggravate the situation with human health. (We know the subject is on Human Health, so you don't need to state it again)

And (Don't start a sentence with And) Thirdly, and very importantly, third and very important: our innovations in medicine and pharmacy have another dark side. Everybody knows that all every medicines have has adventitious adverse/sideeffects. And when we are thinking think that we can cure our ailment, we harm something else hit another organism system, and after some time we again find again nearby similar symptoms. Modern medicines do not destroy illnesses, instead, they only stop symptoms for some  a certain time, because pharmacy is a business, our diseases are somebody's money. The Bad news, that is that next time you will need stronger medicines because viruses develop produce themselves immunity. Stronger medicines-stronger viruses, it's closed  a vicious cycle circle. Also polluted environments  expose new and mutated viruses exposed viruses are mutate, and so nobody knows what new ailments will reveal it themselves tomorrow.
So that's why I'm thinking that humans is are not more healthy than years ago. Humans is are sicker and more defenceless now.
