Mais quelle beauté !

Cette scène montre une bataille de boules de neige filmée en France en 1896 par les frères Lumière, véritables pionniers du cinéma. On y voit un instant de vie simple, joyeux et presque anodin, mais rendu extraordinaire par le fait qu’il a traversé plus d’un siècle.

La vidéo a été colorisée et sa vitesse ajustée, ce qui donne une impression troublante de proximité : soudain, ces silhouettes du XIXe siècle ne semblent plus si lointaines. Elles rient, courent, jouent, se chamaillent dans la neige… comme si le passé reprenait vie sous nos yeux ❤️🙏

Thanks to Matt Walker for correcting the record about biphasic, aka segmented, sleep prior to the mid-1800s. It was not, as he points out, a universal form of human slumber. It was, however, as my publications have argued, the predominant form of sleep throughout preindustrial Western Europe during all seasons of the year. And it was at least as old as the writings of classical authors, including Virgil. Moreover, an indeterminate number of cultures on continents, other than Europe, experienced biphasic sleep. More than two hundred references, not mere "mentions," which, with few exceptions, were not included in my publications may be found on my website : https://t.co/7jsMbRuYu9 . .

Sleep Disturbances and Dementia Risk in Older Adults: Findings From 10 Years of National U.S. Prospective Data - American Journal of Preventive Medicine https://t.co/zF1gF5TwSm More time awake, even at night, may allow older adults to spend more time enjoying social and physical activities that can replenish or maintain their cognitive reserve. This extra productivity may be the mechanism by which those with sleep-maintenance insomnia reduce their own dementia risk over the years.
