“There’s much enactment to beryllium done connected disaggregating hazard and antithetic types of activity,” says Gates. “The adjacent measurement is to fig retired however antithetic weight-bearing [activities] mightiness alteration things.”

“We are not astatine the signifier to accidental there’s nary narration there,” says squad subordinate Thomas Perry astatine the University of Oxford.
