A friend of mine is on a 25 year running every day streak. He flew to Australia and landed 2 days after taking off and said that day “never existed for him” ¯\_(ツ)_/¯

I like your friend's rule. If a guy literally runs every day, through stress fractures, flu, winter snow, thunderstorms, etc, I'm going to cut him a break on an international flight and continue to celebrate his streak with him.
