High Five By 55

A random wondering this morning. I'm wondering if I should look into some kind of hypoxic chamber device and set up for my desk and work area. I've done just a touch of reading into the benefits, or lack thereof, of hypoxic chamber training and have mostly eschewed the idea. This has largely been due to cost, and secondarily due to the research seeming to be less than compelling even leaning on potentially not beneficial when factoring in sleep disruptions and slower recovery times. However, in a decade long project, perhaps some of that concern slips away. And I sit at my desk all day. Could I use a hypoxic chamber around my desk and have it running for hours at a time when I'm not in a meeting or on a call? No sleep disruption of a bed based device. (My wife would never go for the idea of sleeping in an oxygen depriving device anyway!) The slower recovery would still be impactful, but with a training arc viewed over a 10 year period, what's a few extra hours of recove...

One of the things on my mind as I think about the High Five By 55 project is putting together a list of skills it would be helpful to build before I try running High Five. I'm not sure what needs to be on this list. I have some items I can think of right away, but more wondering about those things I don't know that I don't know. Wondering about those is what will keep me up at night. So, I'll try to figure out what those unknown unknowns are over the next several years. And I'll get started by putting together my Big List Of Skills that I want to or need to develop. The list so far: - Wilderness safety - my thought is to take a NOLS Wilderness Safety course. Unfortunately, those are not really offered locally, so I'll have to do this during some travel - Understanding rock quality - for the two class 3 climbs, I think it would be helpful to be able to identify between good rock and rotten, crumbly rock - Reading the weather - it'd be great to be really stron...
