It is impossible for me to believe this has no effect on us, even if subconsciously. Our uplifted spirit is more than psychological. For example, in men of the northern hemisphere, testosterone levels are higher in autumn than even the spring, supposedly the season of love. There is a malady known as seasonal affective disorder, a depression resulting from the change of season. Typically, it accompanys the onset of autumn and winter.
Some scientists say heat is a factor, too.
Napoleon, braced by this weather, foolishly pursued the Russian army into the teeth of deadly winter of 1812. And yet, nobody ever made wiser and bolder use of a break in the weather than Eisenhower in June 1944. Our own decisions need not be so dramatic. This one is really too heavy, but it will be good to wear again. The feel of sleeves on lower arms, and socks on feet.
