Hair Regrowth Update 2016

Two-and-a-half years ago I received an email from a young man named Rob who was developing a hair regrowth technique based on intensive, long-term scalp massage. He had read my post Modulating Testosterone Levels (For Men) and had some thoughts about DHT and hair loss. Rob agreed that male hair loss resulted from DHT shrinking/inactivating hair follicles, but he disagreed that hair loss had anything to do with circulating levels of DHT. It was the accumulation of DHT in the follicle due to reduced blood supply and calcification of the scalp that caused the problem.

This theory matched my intuitive observations. My own hair loss, starting in my early thirties, hadn’t coincided with raging male hormones, but rather with an unhealthy period of my life that included too much alcohol, many late nights, a high carbohydrate diet, significant weight/fat gain, and most likely lower levels of testosterone and DHT. Just an n=1 observation, but the idea of a direct correspondence between hair loss and circulating DHT left something to be explained. I was intrigued by Rob’s idea.

How I’m Voting

An AC Transit bus that helped deliver seniors to the polls in the 1990’s,

This year I’ve decided to share how I’m voting, as an experiment. Sometimes I just ask my wife how she’s voting, and copy her (since we agree on most political issues, and she always does the research), but this year I actually did the research myself. I’ve tried to make notes that get to the crux of the issue, at least from my own perspective. My bias is generally liberal, leaning libertarian on personal freedoms, leaning social democrat on economic policy. I’m more of a pragmatist than an idealist, and for political decision making I favor an empirical approach (what has worked before in similar situations/environments).

I don’t expect anyone to agree with all of my choices, but maybe some readers will find the information to be helpful in making their own choices (somewhere out there is my perfect “mirror-image” voter: one who makes the opposite choice in every category). I hope you find my notes to be useful, even if you end up voting a different way. Let me know in the comments.

Many forms of Government have been tried, and will be tried in this world of sin and woe. No one pretends that democracy is perfect or all-wise. Indeed it has been said that democracy is the worst form of Government except for all those other forms that have been tried from time to time.… – Winston Churchill

Vitamin D and Other Immune Regulating Therapies for Schizophrenia

Brain tonic!

Brain tonic!

Within the last year the understanding of schizophrenia has advanced considerably. Most notably, the origins of the disease have been traced to an overactive expression of the C4 (complement component 4) immune system protein, which is responsible for tagging neurons for “pruning” (destruction) in the adolescent and young adult brain. This “overdrive brain pruning” leads to the devastating symptoms of schizophrenia (delusions, hallucinations, difficulties in planning and life management, paranoia and social isolation). Earlier research, in 2014, linked ultra-high-risk individuals (in terms of developing schizophrenia) to overactive microglial activity. (Microglia are the macrophage immune system cells of the central nervous system, destroying “plaques, damaged or unnecessary neurons and synapses, and infectious agents.“)

Eight Months Without a Car, Cost and Convenience

The eight-year-old’s bike.

Back in February when Kia and I turned in our leased Fiat 500 and decided to do a “one-month experiment” of living without a car, I suspected that the experiment might last longer than one month. But eight months? No way. I was sure we’d have another car by now. But it turns out there are a few advantages to not having an expensive hunk of metal to care for, including:

  • On average, it’s cheaper (about $150/month less).
  • It’s great to not worry about your car (will it break down or get stolen/scratched/dented/broken into/ticketed).
  • We save time on car maintenance and paperwork.
  • All three of us are fitter, stronger, and leaner (details below).
  • I feel more physically and socially connected to my neighborhood.
  • Our carbon footprint is reduced (though still high — we sometimes fly on airplanes).
  • I get to use my phone like a magic wand to summon friendly drivers to my house who arrive within minutes and take me wherever I want for a reasonable price and I don’t need cash not even to tip (thank you Lyft).
  • Local grandparents have been great sports about having to drive a bit more (thank you!)
  • Given our situation (we both work from home, our kid goes to school three blocks away, our neighborhood has a Walk Score of 91/100, local car-sharing options), we’re pretty much the ideal family to NOT own a car.
