Solera - Wikipedia
Fascinating stuff -- from Felix Cohen's excellent twitter thread.
Solera is a process for aging liquids such as wine, beer, vinegar, and brandy, by fractional blending in such a way that the finished product is a mixture of ages, with the average age gradually increasing as the process continues over many years. The purpose of this labor-intensive process is the maintenance of a reliable style and quality of the beverage over time. Solera means literally "on the ground" in Spanish, and it refers to the lower level of the set of barrels or other containers used in the process; the liquid (traditionally transferred from barrel to barrel, top to bottom, the oldest mixtures being in the barrel right "on the ground"), although the containers in today's process are not necessarily stacked physically in the way that this implies, but merely carefully labeled. Products which are often solera aged include Sherry, Madeira, Lillet, Port wine, Marsala, Mavrodafni, Muscat, and Muscadelle wines; Balsamic, Commandaria, some Vins doux naturels, and Sherry vinegars; Brandy de Jerez; beer; rums; and whiskies. Since the origin of this process is undoubtedly out of the Iberian peninsula, most of the traditional terminology was in Spanish, Portuguese, or Catalan.

Put Down the Pink Dumbbell
So, ladies, let’s first put down the two-pound, pink dumbbells. We have been sold a false story about fitness, health (and its connection to weight loss).
I was exercised by wolves. And I’m going to tell you all the secrets and tricks I learned by avoiding the fitness-industrial complex.
Most of what I’ll say applies to men, but I have discovered that most of the outrageously wrong advice is given to women. [...]
So, here: truth number one. Very few of us consider strength-training as essential exercise, but it is. It is especially crucial as one ages, because a natural part of the aging process is losing muscle. Women, especially, need to lift weights, and the trick to lifting weights is stressing muscles. And that weight has to be a real weight, progressively increased, and barring health issues, an average woman should not even bother with two pound weights because that won’t stress your muscles enough to benefit you.
Exercise industry is surely partially to blame for why people don’t exercise regularly: they promise the wrong thing (weight loss) and then don’t push/guide people to do the right thing.
