Many retirees in your position find this to be the perfect time to learn a new skill or take classes at a local school. It is not uncommon for colleges and universities to offer continued education classes to seniors for free of charge or heavily reduced prices. This means that now could be the perfect time for you to brush up on your old passion, whether that means Biology, English, or any of the elective courses that most schools offer. Consider reaching out to a college near you to see what offers they have available for seniors.
