Normally when you see young people taking large doses of NSAIDs, it's because they're either elite athletes or have an autoimmune disease or something.
There are enough people who have no idea that hang-over + pop-2-advil is a deadly combination in this situation.
Also a lot of the "new year, new body" resolution folks start too hard at the gym & then push through with NSAIDs.
Young people, particularly the fit, do go through a lot of NSAIDs out of OTC convenience.
Taking 2 ibuprofen in a day against a flu like headache is what your doctor recommends, probably. Not exactly a massive amount even if repeated for a week.
