Here's a potentially relevant quote from "The Man Who Solved the Market" by Gregory Zuckerman[0].
"One day, a data-entry error caused the fund to purchase five times as many wheat-futures contracts as it intended, pushing prices higher. Picking up the next day’s Wall Street Journal, sheepish staffers read that analysts were attributing the price surge to fears of a poor wheat harvest, rather than Renaissance’s miscue. [...] “Any time you hear financial experts talking about how the market went up because of such and such—remember it’s all nonsense,” [Peter] Brown [CEO of Renaissance Technologies] later would say."
Here is what Buffett says about value investing (in his 1992 BRK shareholder letter):"In addition, we think the very term “value investing” is redundant. What is “investing” if it is not the act of seeking value at least sufficient to justify the amount paid? Consciously paying more for a stock than its calculated value—in the hope that it can soon be sold for a still-higher price—should be labeled speculation (which is neither illegal, immoral nor—in our view—financially fattening).
Whether appropriate or not, the term “value investing” is widely used. Typically, it connotes the purchase of stocks having attributes such as a low ratio of price to book value, a low price-earnings ratio, or a high dividend yield. Unfortunately, such characteristics, even if they appear in combination, are far from determinative as to whether an investor is indeed buying something for what it is worth and is therefore truly operating on the principle of obtaining value in his investments. Correspondingly, opposite characteristics—a high ratio of price to book value, a high price-earnings ratio, and a low dividend yield—are in no way inconsistent with a “value” purchase."
Here's a link[0] to my (non-monetized, WIP) blog about Renaissance Technologies[1] who were one of the first ones to use statistical arbitrage. Others were D.E. Shaw[2] and Pete Mueller at Morgan Stanley (later PDT Partners[3].)
This comment made me think of the tax advantage of buy-and-hold versus lots of small bets. Buffett also talks about this in his Berkshire shareholder letters.[0]
I collected some info on Rentec in my blog[0] because I wanted to find out more after reading Zuckerman's "The Man Who Solved the Market." I hope you find it useful.
Full disclosure: I have no medical training whatsoever.
Exercise (a combination of cardio and resistance training) seems to be a very, if not the most important thing. That's the takeaway from two podcasts I listened too recently.
In the first one[0] Stuart Phillips talks about how important resistance training is for older people. He also says that if you exercise then supplementing your diet with protein is really just the "sprinkling on top". Doing the exercise is far more important.
In the second[2] one the author (who was diagnosed with MS in her 20s but is not taking any medication and is now 58) exercises every day (mostly running, 3-4 miles). The podcast was about her book in which she sums up a lot of research on diet vs exercise. The conclusion is that as long as you exercise it's not very important what you eat. You don't have to be vegan, vegetarian, or follow any other special diet. They talked about, e.g., world class athletes with completely different diets, all performing at peak levels. Again, exercise seems to be the far more important, common, denominator.
Regarding supplements:
(I took this from my personal notes, that's why there are recommendations, they are for myself [a healthy adult in middle age]. Also, I have no affiliation with any companies/products mentioned):
Resveratrol exists in two molecular arrangements: trans- and cis-
- Trans-resveratrol is the predominant form found in most supplements, and also the more stable (but if exposed to light, it can convert to the less-active cis-resveratrol)
- Trans-resveratrol is more bioavailable if taken both in the morning and with food
- More data is needed to determine resveratrol’s effect on exercise
- Resveratrol activates a variety of anti-inflammatory and antioxidant response pathways
- Resveratrol is a calorie-restriction mimetic
## Resveratrol in exercise
The data surrounding Resveratrol and exercise is contradictory
- At a low dose, resveratrol acts as s a mild direct antioxidant (which bind to and sequester reactive oxygen species)
- This isn’t preferable – the reactive oxygen species generated during exercise are essential for cardio-respiratory adaptations
- At higher doses, resveratrol seems to act as an indirect antioxidant (which activates the body’s own endogenous antioxidant systems, like glutathione)
## My takeaway
- Take a higher (500mg or more per day) dose of Trans-resveratrol with lunch (because I'm currently 01/2020 still sticking to my time-restriced eating; no food between 8 PM and 12 PM).
