I'm not going to add any commentary on the paper, other than to say that the risk ratio for all-cause mortality for moderate drinkers in the six high-quality papers they identified is indistinguishable from zero.
In other words two to three drinks per week has not been identified net causing any harm, at least in epidemiological studies.
A lining of triangular foam blocks would make for an interesting pool. It might work, but practicality (installation, cleaning etc.) would likely rule it out
Well before that the hydrogen atoms would fuse into helium and release vast amounts of energy, killing all the swimmers, spectators, and many people in Paris.
Slow pools absolutely exist, as wave drag is the major impediment to speed and contributes about 55% of total drag. A shallower pool has more reflected wave energy in all directions. 2m is very shallow for a competition pool.
It seems to matter to those deciding where to put their early-stage venture capital. Granted, that's not why most people are going to college, but it's too simple to say that it isn't used as signal.
