Ciao, Not exactly in my 40s, but I started a bachelor's degree in Computer Science (in Italy) just five years ago, at age 35, while working, and I completed it successfully last April! It was tough; I invested much of my free time into it, especially during the first years with mathematics! My advice is not to fear failure, don't be impatience, take your time and go on. It doesn't matter if other students are faster or pass multiple courses at once; find your rhythm, do one thing and do it well, and everything will be fine.
