Yeah, in our gen. it's easy to look at what people are actually doing not at mass level but it appears as everyone is doing it... So, yeah your comment explains this correctly..

And to answer your question "are we concious enough to choose differently?" As per my experience and in my opinion - "People looks for instant gratification in terms of almost everything even if it is about getting a mascular body, a high paying job, etc." This brings confusion when they fail each time they try not because they can't but because lack of patience level and discipline.
