⌚ Fitness devices are great.

These ever-popular holiday gifts can tell you how far you have walked, run, cycled or skydived, and will let you know whether you’re getting enough rest, sleep or downtime.

But is there a risk? trib.al/IfpVoPW
With ever more data being collected from our bodies, gadgets from Apple, Garmin, Fitbit and dozens more are starting to assert their own opinions about how we should live our lives.

The feedback might be doing more harm than good trib.al/p8l8xl2 A picture of an Apple Watch series 3.
There is a term for this phenomenon: the nocebo effect.

The opposite of a placebo, a nocebo delivers otherwise benign information that can actually reduce your sense of well-being.

Will you or a loved one truly benefit from 24-7 monitoring? trib.al/p8l8xl2
Research on the nocebo effect has shown that perceptions of pain can increase with shifts in information and detail.

Concentration falters when unpleasant data is provided trib.al/p8l8xl2
With more devices strapped to people’s bodies, nocebos are now creeping into every day life as people put more faith in data to guide their habits trib.al/p8l8xl2 A quote card from Ali Spagnola, a fitness producer and Youtu
While a constant flow of data can help people optimize their health, the opposite can also be true.

Fitness podcaster and Youtuber @alispagnola says sometimes all we really need is positive reinforcement trib.al/p8l8xl2
The nocebo effect has become inherent in social media.

Rather than logging on to feel inspired and connected, Instagram has made users feel anxious.

The constant feedback of likes and retweets has undermined what should be appreciations of creativity trib.al/p8l8xl2 A picture of a blonde female and brunette male posing for &q
Well-meaning executives who churn out gadgets and apps place a high degree of faith in their products’ ability to improve life.

They rarely stop to think about the downsides trib.al/p8l8xl2

💍💸 Most people believe that marriage is an economically beneficial arrangement.

That’s not always true bloomberg.com/opinion/articl…
Take student loans, for example.

There is more than $1.57 trillion in outstanding federal student loans in the U.S.

If you get married and file a joint tax return, your spouse’s income will be included in the calculation for how much you owe.

If both parties have debt and are on income-driven repayment plans, this payment hike could be lethal for a household budget trib.al/QkqXKw1

Not everyone is thrilled by Time’s choice for “Person of the Year,” but it’s hard to deny that 2021 has really been Elon Musk’s year.

Let’s run through the highlights trib.al/g4CfsgL
.@elonmusk is now, on paper at least, the richest person in the world, gaining more wealth in 2021 than Berkshire Hathaway made in revenue trib.al/ju1uIo0 bar chart of net worth of richest people in the world
@elonmusk In fact, although Berkshire Hathaway delivers America’s best profits, Tesla’s market cap is way bigger than Berkshire’s. Make sense?

Maybe not in a traditional sense, but this is Elon Musk’s financial market now trib.al/ju1uIo0

🏠 The housing market is surging again.

But why is it upshifting during what should be the slowest time of the year? One answer is rising prices in the rental market trib.al/EJ4bwO9
Leases that are coming up for renewal now were signed at the end of 2020, before rents exploded higher.

That's renewing interest in home buying, which is essentially pulling the 2022 spring home buying season forward by several months trib.al/svEWcoh A picture of many houses lined up
If there's a silver lining for renters, it's that the cycle might relieve some of the upward pressure on rents that we've seen for most of 2021 trib.al/svEWcoh

The enduring debate in the crypto community is whether Bitcoin will outperform “altcoins,” which are generally defined as digital currencies other than Bitcoin, such as:

🪙Ethereum
🪙Solana
🪙Cardano
🪙Polkadot
trib.al/Lm8n25y
It’s true that Bitcoin is perfectly decentralized and the number of coins that can be in existence is limited.

But the real question is whether crypto investors necessarily need a true store of value, or whether there is space for multiple blockchains trib.al/Lm8n25y Image
Consider that 2,000 years ago the financial system consisted mainly of gold.

🚫Bonds didn’t exist

The change of expert opinion was sudden.

Researchers at Harvard Medical School now say the omicron variant, not delta, is likely fueling the current surge in Covid-19 cases in the northeastern U.S. trib.al/O49sJhb
That’s cause for alarm, because researchers still don’t know much about the variant, and it’s unclear how well vaccines will protect people.

Harvard’s labs are optimized for speed but omicron is spreading faster than they can track it trib.al/O49sJhb Man walks in holiday market with mask on.
“I think we are in the omicron surge,” Bronwyn MacInnis, director of pathogen genomic surveillance at the Broad Institute of MIT and Harvard said.

Mark Zuckerberg has bet the future of his company on the “metaverse” becoming the place where we’ll connect with family and friends.

But what’s it actually like socializing in virtual reality? @parmy found out trib.al/ioKkM1R
@parmy Over two weeks, @parmy mingled with people at an array of virtual locations including a:

🎶Concert
⛪️Church service
🎙Conference
⏲Speed-dating event

Connecting with people in VR is fun and exciting, but it’s also intense, tiring and often awkward

@parmy Meta's VR platform Horizon Worlds just opened to adults in the U.S. & Canada. But its precursor, Horizon Venues, was full of kids.
