In 20 and 200 years to come people will not grow older anymore as they would invent a machine that will reduce the age of human being, now age will just be a number even with more days, months and years passing and passing man will have advantage over it by determining the age which he/she wants to be.
Also in 20 and 200 years to come people will no longer wear clothes as we almost watch in televisions and in the internet some people has already adopted this method but now it is not mostly seen as most people's in the world still not accepted it and seen it as a nonentity, but the musicians, actor's and actress don't see it that way as they are the ones that practice this doctrine nowadays.
I also predict 20 and 200 years to come in the aspect of climate and weather Control:
They will be a universal climate and weather change for each country, and this will happen in the sense that climate and weather condition will now be a choice by everyone, you can choose what weather or climate condition you need in a particular point in time.
Lastly, I see a world of a better tomorrow where they will be no more blood shade between countries both internal conflicts and external, I see a world of mutual understanding and Love.
Thank you for reading, see you next time.
