In 2018-19, I led a team of researchers to quietly investigate this and found that the Roulleaux formation was directly caused by holding a cellphone.
We tried to generalize and failed.
That doesn’t mean there isn’t an effect, it just means we couldn’t model.
More recently, I quit wearing my Apple Watch due to mild neuropathy in my left hand. It appears that the effect has to do with stress but not with direct genomic problems. Kudos to this team for their success.
Watch out for these electronics we all love so much. Imma go buy a wired headset.
