Ten years ago I bought a home-sauna with infra-red heating. I didn't find it satisfactory. I would get bored and restless, waiting for the sweat, and, when I moved, it stayed in the old house. The best saunas IMHO are wood-fired saunas where you can safely toss a liter of water on it and get that rush. Keep up the excellent writing, David.

(I was disappointed to discover [in the Longo book] that I am too old to take advantage of his faux fasting diet)

I was previously aware of saunas of course, but always considered them a fetish for perverts until I found Sinclair's mild acknowledgement and his connection to the biology of aging. So I studied it more, decided to try it, and have found it useful. I go most every day, with a 25 minute session and 10 minute drive both ways and that cold shower kills an hour. But it's a good time for contemplation and occasional socializing and seems to be helping my blood pressure, as well as other benefits I haven't quantified yet. So it seems a reasonable experiment to continue. I hadn't really considered infrared until researching this article. I suppose a traditional Finnish sauna would entail a lot of maintenance, and IR much less, so I might try one.

I'm not inclined to accept conventional geriatric wisdom. My cardiologist put me on a mild fasting diet 3 years ago at 70, which I improved more like the Longo prescription, as a tool to improve my homocysteine, which is an alzheimers risk. So I've taken fairly aggressive lifestyle steps despite conventional wisdom, and it seems to be working. I'm the oldest student in my jiu jitsu gym. My instructors are aware of my conditions and are careful about my progress, but they encourage me to find and extend my limits. First rule of survival is never give up.

I speak only geriatric wisdom and I believe only geriatric wisdom. I am a cache of geriatric wisdom and I'm not certain disco will end rock and roll. #GoNukes #Let'sGoBrandon
