Consider that an undergrad takes 4 years, with a 2 year master's on the end of it, but that's for students who are distracted. You can completely reinvent in 3-5 years, and at that age, you will have condiments in your fridge that have lasted longer.

Can't say much for finding jobs, as I've contracted and consulted for most of my career because I prefer the problems and change, but really, your options are either to manage, or become manageable. That's the decisive factor in finding a job as we age, imo.
