There's a pretty good sci-fi movie with Bruce Willis (made before his career sunsets 🙂) - Surrogates, about a future where people live partly "online" in a virtual world, while their bodies get fat and old somewhere in a dusty apartment. The movie echoes the ideas of various sci-fi writers Strugatsky, Lem, Lukyanenko.... However, even these guys would be surprised to see how we've all been "digitized" in a time of covid restrictions. Studying, working, socializing, dating - all this has found a new fashionable format "online"
Perhaps some of you think that this is progress, but I will be in solidarity with the protagonist for whom what is happening in the story was a dystopia🙂 I'll try to explain from the point of view of biology what will happen to us in the world "online":
1️⃣ The online format of work/study leads to a kind of social isolation, which in turn can lead to depression and other mental disorders due to a decrease in BDNF nerve growth factor and levels of certain neurotransmitters. To understand this, go to a zoo and compare the sight of single animals and the sight of those in pairs/groups 🙂
2️⃣ Online format leads to a decrease in physical activity, hence problems with blood vessels, lymphatic outflow, and this is varicose veins, hemorrhoids, prostatitis and other vile diseases that used to be only in old people.
3️⃣ "Online" leads to persistent vitamin e deficiency.
4️⃣ Due to the reasons described above, a person's immune system becomes less active ("stay home, stay safe" is the slogan of idiots)
5️⃣ Online leads to weight gain at the expense of fat because no energy is expended and access to food is unlimited.
6️⃣ Guys who work online for a long time without "live" contact with girls have a drop in testosterone levels and a rise in prolactin levels (I call it the IT guy syndrome 😄) This is partly why "macho guys from tinder" may not understand how to behave with girls in real life. Similar processes also happen in girls who live Instagram.
7️⃣ Constant eye strain behind a display causes myopia. 👓
8️⃣ Due to constant sitting at the computer, the correct posture is disturbed (text neck, kyphosis, scoliosis, protrusion, hernia).
All these points lead us to accelerated physical and mental aging. Remember this and try to be "offline" as much as possible 😉
