Replaced the gas cylinder in my Aeron and now it’s working like new

So I’ve had an Aeron chair for my home office for well over a decade and it’s been a great chair, but recently it started just sort of sinking from time to time. Turns out the hydraulic gas piston was giving out. So I ordered this replacement piston for $20 off of Amazon:

It came yesterday, and I found myself watching a multitude of videos on YouTube to try to determine how to remove the old cylinder, which after 10 years of my heavy ass sitting in it, was firmly in place. Turns out all I had to do was load the bugger up with WD-40 and let is sit over night. This morning, I took the pipe wrench to the thing and with a few twists it was free. Then rubber mallet to the bottom to remove it from the base. I slid the new one in, turned the chair back upright sat down and pffffffffffffff

It immediately deflated. I thought the new cylinder was defective at first and began a return for it, but then I noticed that the button on this model was a little taller than the one that I’d just removed. Popped the base of the seat off, loosened the little button depressor with an Allen wrench, and voila!

I put the seat base back on, sat down, and found my old chair sitting firm and tall like it used to back when I first bought it. Not too shabby for $20.

Body & mind hacking

So as someone who used to help run Hackaday when it was under Mahalo’s wing, led Chaotic Moon’s Labs where we did innovative combinations of technology to think about existing technology in new ways, and contributed to and authored my own O’Reilly hacks book, I have mixed feelings about how the term “hacking” is applied currently across a large stretch of non-technological topics.

However, recently, I’ve been reading up on the science behind and trying out a few of the things that are currently categorized popularly as “body hacking” and “mind hacking.”

Several weeks ago, I began attempting to adopt intermittent fasting, after reading several blog posts about it that then led me to actually read some of the research behind it. Basically, I try not to eat any food between 6pm at night at 10am the next morning, compressing all my active intake of food to an 8 hour window. This is extremely hard to do, I’m only about a month into the experiment, and so far, I’ve been forced to break this several times due to social obligations, and broken it myself due to it being difficult. So I don’t think all my organs have had a chance to sync up all their internal clocks for me to see the best results from this, although I am still trying. We’ll see if I get better at it. I’d love to hear what others who have tried it have experienced.

Last night, I ended up watching this TED talk featuring Wim Hoff:

Then I watched some more videos on Wim Hof, his breathing method, and then bought Scott Carney’s book on Wim which I started reading last night on my Kindle. It’s all very interesting. I just practiced my first attempt at his breathing method this morning, so we’ll see how it goes. It felt relaxing for sure, but way too early to tell if it really works or not. I’d love to hear from others who have tried this, gave up, think it’s horrible, or swear by it.

In any case, I’m experimenting a bit with these things as I get older and get tired of always having colds and allergies. We’ll see what happens.

UPDATE: Check out this other Wim Hof video I just found during lunch:


AND ANOTHER UPDATE: Sorry I can’t stop updating this post, but I keep finding other cool videos with more information:
