Quirky traits you didn’t know you can inherit!
Early bird: A 2019 study found that people are probably genetically predisposed to be morning larks or night owls.
✓ Coffee obsession: A study found that those with more of a certain gene drank less coffee, maybe because they metabolize caffeine slower, so they need less of it to feel happy and awake. (Freaks…)
✓ Trust: A study of twins found that trust in others is 30% heritable (which is, apparently, a word). Distrust, oddly, is not an inherited trait and “appears to be primarily socialized”.
✓ Sweaty hands: It’s not all nerves. Researchers found that 2/3 of patients with “sweaty palms syndrome” have a family history of it. (I’m much more comfortable about this now that I haven’t shaken anyone’s hand for 3 months!)
✓ Sweet tooth: A study found that nearly 80% of preschoolers carried at least one of the genotypes that makes them want to snack on sweets instead of veggies.
✓ Ability to smell “asparagus pee”: Self-explanatory. Not kidding.
