We've been talking about the remarkable health benefits of salmon — which is loaded with omega-3 fatty acids — for a long time.

Now we're delighted to tell you that omega-3s don't just cool inflammation and protect your heart and brain, they also may slow the aging of your biological clock.

A study published in the journal Nature Aging takes a look at three of your body's so-called DNA methylation clocks: PhenoAge, GrimAge2, and DunedinPACE. These clocks reflect various epigenetic changes to your genes that influence gene expression, and they can signal if you're aging quickly because you're losing the ability to fight infections, autoimmune conditions, and chronic diseases.

But the researchers also found that these clocks slow down when you take a 1 gram supplement of omega-3 daily — making it an important component of a "live younger longer" lifestyle.

Even better news: That's not all you can do to stay younger longer.

There are more than 40 ways outlined in "The Great Age Reboot" and on LongevityPlaybook.com. Get started slowing down time with these four steps:

1. Reduce stress by having a posse, a purpose, and good sleep habits, as well as by practicing meditation.

2. Perform aerobic and strength-building activities weekly, aiming for a minimum of 30 minutes five days a week.

3. Ditch all added sugars and syrups, red and processed meats, and highly processed foods.

4. Practice generosity, and focus on what you are grateful for in your life.
