By Kay Dawson. I went back to school at the age of 59--and I’ve learned a lot more than Spanish. Books are heavier. Combining a caffeinated soft drink and a two-hour class with a 59-year-old bladder is not a great idea. Professors are so young. But what seems to have changed the most from when I was last in school is that it is no longer possible to go to college on a shoestring.
