IFLScience spent a night at a famously haunted British castle and came back with a better question: why do people pay to be scared? Scientists call it recreational fear, and it works because the body treats fear and excitement almost the same way. Also: a study of 57,793 older adults in 24 countries links staying socially active, especially volunteering and sports clubs, to better memory and thinking over time. And NPR reports that a median-income renter would need 16 years to save for a starter home, twice as long as in 2019. Plus a runaway kangaroo, a Texas man who returned $128,000 he found on an ATM, an extinct tiger head found under a bed, and scientists who nuked an asteroid in a computer.
