There are quiet a few disadvantages using too much Internet. What I feel ,we read less books if we use Internet too much because whatever answer we need we just type it in google and take out the answer. It has made us lezy and reluctant of knowing other related staffs and language.and I also think using too much Internet increases eye problems to a great extent because I am suffering of it already. Good Luck and be healthy.
Ah, probably that we can get caught up with it and spend too much time on the internet. Time seems to slip by very quickly when I am on the internet.
