In 2021, people created 2.5 quintillion bytes of data every day. Experts predict that by the end of this year, we'll produce and consume about 94 zettabytes (just one zettabyte is 1 sextillion bytes) of data.

No wonder it's hard to sort out health news you can use from the daily onslaught. To help, here's my roundup of three new insights that can simplify your goal to live longer, younger, and happier:

1. Regularly taking NSAIDs or getting cortisone shots to ease knee pain and, you hope, avoid a total knee replacement (TKR) actually speeds up joint erosion. That's fine if you're planning on TKR but want to put it off a while. But not if avoiding surgery is a medical necessity. In that case, physical therapy and/or less invasive surgical repair may be better options.

2. Feeling bad about your body? Head outdoors. U.K. researchers found that spending just 40 minutes being active in nature (even when there's no green to be seen) results in greater body appreciation and that translates to less self-criticism and anxiety about how you are perceived.

3. COVID-19 news. Despite what misleading headlines have declared, repeat infections of COVID-19 are far less severe and fatal than first infections. What does increase COVID-19-related risks? Obesity makes it more likely you'll get long COVID-19.
