“Many many years ago – possibly 50 or so – housewives made use of to say that when they obtained hot gardening or undertaking something outside, they would appear in and operate their fingers under the cold faucet,” Tipton discussed.
“So when we have been seeking for a little something for the Navy firefighters who have to go into very very hot compartments wearing a ton of protecting clothing, you start off with how the human body will work. And we located that sticking their arms into chilly h2o was as helpful as everything else we could do for them.”
