Can't speak for OP, but as someone who's getting close to 55, it is a chance to revive an interest that's always been there and a talent that hasn't been completely exploited elsewhere. Other business/financial affairs are not needing a ton of supervision at the moment, and so pursuing a degree might actually provide a decent financial return by preventing silly investments made out of boredom. In addition to postponing dementia, of course.
None of these concerns will likely seem relevant to anyone under 30.
