Health Check: does caffeine cause dehydration?

1 Share
By Ben Desbrow, Griffith University For a long time people have been told that caffeine is a diuretic. For some, this translates into advice to avoid or remove caffeinated beverages from the diet of people at risk of dehydration, or during periods of extreme summer heat. While possibly well meaning, this advice is wrong. By […] The post Health Check: does caffeine cause dehydration? appeared first on Sciblogs.

50% of people who lived in 1917 were intellectually disabled

1 Share
More than half the world was intellectually disabled prior to 1917CE….. if you extrapolate the Flynn effect. This blog will be an interesting dive into IQ, intellectual disability, crime, time travel and the Flynn effect. Let’s start by saying that you are probably “smarter” (whatever that means) than your parents. That’s right, when you were […] The post 50% of people who lived in 1917 were intellectually disabled appeared first on Sciblogs.

Furniture Design History: Why Do Wingback Chairs Have Wings?

1 Comment and 11 Shares

If form follows function, then to the modern-day observer, the design of wingback chairs does not appear to make sense. Why add structure to, and upholster, the sides of a chair above the armrest? The sitter needs no lateral support and is not likely to even contact the wings in regular use.

The answer has to do with climate control, or more precisely the lack of it, in 1600s Britain, where this chair style was first invented. Lacking weatherstripping, caulk and triple-glazed windows, houses and buildings of the time were drafty affairs. The wingback chair was designed to be sat in front of the dominant heating method of the time, fireplaces, while the wings on the side prevented drafts from slicing through your little cocoon of warmth. The pronounced protrusion of the wingtips was to keep the breeze off of your ears and neck.

The earliest versions were made completely of wood, and upholstery was sparse.

Even when the chairs first did become fully upholstered, it was more springs and horsehair than plush polyurethane foam, as you can see in this cutaway.

Nowadays wingback chairs can be had in all manner of garish patterns, and with stuffing up the yin-yang…

...or in versions where the materials choice makes no sense given the original context.

To my eye, the classic leather ones look best.

In any case, now you can see that Arne Jacobsen's egg chair, when it came out in 1958, must've looked like the new VW Bug of its day: A modernized nod to the past.

Shouldn't we always treat people with respect until they no longer deserve it?
