It’s no surprise that having close friends or family members can help us lead healthier, happier lives. But did you know that being lonely can literally make you sick? According to an article by Dr. Sanjay Gupta in O, The Oprah Magazine, loneliness can increase your risk of mortality by 45 percent. In contrast, obesity raises your mortality risk by “only” 23 percent. One study found that seniors who are lonely are 64 percent more likely to develop dementia. Feeling cut off from extended family, working increasingly longer hours, interacting online instead of face to face—any number of factors can lead to loneliness. No matter what your situation, here are five things that you can do to connect with others and make a difference for animals.

Volunteer at an animal shelter: Whether you walk dogs, groom cats, clean cages, stuff envelopes, or help with a fundraising event, you’re bound to make many new two- and four-legged friends at your local animal shelter.

Help a homebound neighbor: Is someone on your street sick or homebound? Chances are he or she could use a helping hand. Offer to take the person’s dog for walks or to clean up after his or her kitty, or make the day brighter by providing a homemade vegan casserole.

Get crafty … or clubby: Are you a knitting ninja? Do you know your way around a sewing machine? Why not form a craft circle that makes toys or blankets for animals in shelters? It could be as simple as visiting Meetup.com and signing up to be an organizer. Or join (or start) a vegan potluck club or animal rights book club. You’ll meet likeminded people, and your social life will get a boost.

Participate in a protest: Grab some leaflets and let others know what’s wrong with the circus, a fur store, or a local roadside zoo. You don’t have to do it alone. Join PETA’s Activist Network, and we’ll help you connect with other animal advocates in your area.

Adopt, don’t shop: If you have the time, resources, patience, and love to devote to an animal companion, consider adopting a dog or cat (or two) from your local animal shelter or a reputable rescue group. Not only will you save a life, you’ll also make a best friend for life.

Bonus tip: If you live in the Hampton Roads, Virginia, area, come to PETA’s weekly work party on Thursday nights. We’d love to see you!
