I'm in my 30s, and somehow people think it's a miracle I don't have bad back problems after sitting at least 6 hours a day in front of the computer, while the only miracle performed is me going to a store to get a personalized recommendation based on how I like to sit, and invest hard in getting a proper chair.

First thing I ask when people complain about bad backs, is what chair they use. Often they've just grabbed some chair after going window shopping, instead of aiming for personalized recommendations from a professional. Often, they're using these shitty "gaming" chairs. Sometimes though, they've just read a bunch of the internet about how good Aeron chairs are, so they bought those, not understanding not every chair fits every sitting style...
