In contrast to Ron, there was a guy, may still be, in Daytona Beach who had or has a streak that wasn't that much shorter than Ron's. But this guy reportedly ran exactly eight miles every day at exactly 5:00 PM on exactly the same stretch of Daytona Beach. The story about him said that he NEVER varied from this routine.
Assuming that's true, you could start wondering if this guy doesn't have some OCD issues. It's possible he doesn't but when you use impairment of ability to function normally as a criteria you have to wonder if he'd like to travel but never "can" because he wouldn't be able to run at that exact section of the beach, has he passed up jobs that he really wanted because he'd have to work a 3-11 shift and be unable to run at 5:00, made family members mad because he skipped a wedding that started at 5:00, is out on the beach running through hurricanes, etc. But even here it's entirely possible that the guy is doing all this because he wants to and not out of fear that if he doesn't something awful will happen.
