Is that peer reviewed? There are exceptioins to every rule.Got mine. 4 times so far since 2021 and have mountain hiked with pack for 11 miles with 4,000 ft elevation change, done a 50 mile overnite kayak trip and skied for a week above 8,000 feet with temps that range from 2 to 18 degrees. I guess my heart is fine, of course I'm no teenager.
