I actually think it IS a function of age. For example, while you personally have more time in your 30s, it's not true for the majority. An average person in their 30s will have experienced more "life" than someone in their 20s, so the chances are higher that they will have added obligations and responsibilities. Whether it's financial responsibilities or familial responsibilities, ignoring how life usually works out for the average person because your situation is different is a bit selfish. As much as kids in their 20s like to think they have their life planned out step by step, life has a way of throwing a wrench into those plans. I don't think its disingenuous at all to assume that people have less responsibilities in their 20s than in their 30s. A personal anecdote to the contrary doesn't really change that.
