1. She’s Healthier As She Gets Older

Nielsen embraces aging. In fact, she says to Us Weekly that she’s in much better shape now than she was back then. “I’ve become a stronger person. I have more energy than when I was younger. And I'm much more thoughtful and prepared." When aging, exercise. "Physical activity increases blood flow to your whole body, including your brain. Studies suggest regular exercise is associated with better brain function and reduces stress and depression -- factors that affect memory," says the Mayo Clinic. "Make sure your diet includes high-fiber foods, such as fruits, vegetables and whole grains. Limit high-fat meats, dairy products and sweets, which might cause constipation. Drink plenty of water and other fluids."

2. She Doesn’t Give Up

Nielsen is extremely determined. She says that this extends to her desire to have children. The actress talked about her journey on the talk show, Loose Women, “It’s about not giving up. It’s not for everybody, it’s a long road, it can be very tough. But women who really dream for it don’t give up, but it’s a long road.”

3. She Uses A Rowing Machine

When Nielsen hits the gym, she likes to use a rowing machine to stay in shape. She posted this photo of herself using it on Instagram. She captioned the photo, “Can I still get a medal somewhere? (Be nice.)” "Rowing recruits many muscle groups and can provide a total-body, cardiovascular, muscle-building workout that you should consider adding to your weekly exercise routine. Rowing is also impact-free and non-weight-bearing, which makes it even more appealing because you can work intensely without putting added stress on your joints," says ACE Fitness.

4. She Bike Rides

Nielsen loves to go bike riding as a way to get moving. She also likes to bring her daughter along sometimes. Nielsen posted this photo on Instagram of herself and her daughter going for a ride. She captioned the post, “That’s how my Sunny Sunday went. How was yours?”

5. She Got The Vaccine

Nielsen made sure to get the vaccine to protect herself from COVID-19. She encouraged her followers to do the same in this Instagram post. She captioned the post, “Call the shots! The vaccine puts you in charge of our future. Get it done!” "CDC recommends COVID-19 primary series vaccines for everyone ages 6 months and older, and COVID-19 boosters for everyone ages 5 years and older, if eligible," says the CDC. "COVID-19 vaccines available in the United States are effective at protecting people—especially those who are boosted— from getting seriously ill, being hospitalized, and even dying. As with other diseases, you are protected best from COVID-19 when you stay up to date with the recommended vaccines."
