In this French‑language YouTube video, Mohamed Boclet warns that human attention spans are collapsing and identifies three everyday habits that literally destroy the brain. 1) Consuming short‑form social media (TikTok, Shorts, Reels) erodes focus; spending more than 90 minutes a day on these formats dramatically reduces concentration. 2) Chronic sleep deprivation – especially binge‑watching series or using phones before bed – impairs cognition, reaction time and can equate to a state of intoxication after 48 hours without sleep (Harvard study). He offers concrete sleep hygiene tips: avoid phones in the bedroom, keep a pre‑sleep wind‑down routine, read a relaxing book, aim for 7.5‑9 hours, go to bed around 22:00 and wake at 5:30. 3) Not exercising the brain. He likens the brain to a muscle that needs regular stimulation through learning new skills (languages, piano, courses) to strengthen neural connections, protect against neurodegenerative disease, and boost memory. Throughout the video he mixes alarming data with practical advice and repeatedly urges viewers to subscribe, share, and comment on how they keep their brain fit.
