I'm 72 years old, healthy, retired for 5 years and completely bored with my life — I want to go back to work but no one wants to hire me because of my age. What can I do?

The only problem, however, is that finding meaningful work at an advanced age can be difficult — especially if there's a gap in your resume.

If you're finding it difficult to get hired, you still have some options.

Work for yourself

If you're more interested in working as a retiree to find purpose rather than to get a paycheck, this may be a good time to explore entrepreneurship. When you aren't dependent on wages to support your family, you can take more time to become profitable and can work in a field you're passionate about even if the pay isn't great.

Try to find a low-cost business opportunity that plays to your skills. Consider things like babysitting, serving as a personal chef, freelance writing, dog walking, pet sitting or tutoring. These opportunities could provide a good work-life balance, as well as the chance to turn hobbies you enjoy into a paying gig.

There are lots of online apps you can sign up for to jumpstart your efforts — or you can learn to create a basic website and advertise in some local groups to find customers.

Volunteer your time

Volunteering is another way to fill your time and potentially get your foot in the door at organizations that might hire you.

You could meet other professionals while doing volunteer work that may know of opportunities for you. Some charitable organization also offer paid positions, and depending on the type of work you do, they may be willing to bring you on if there's an opening.
