Head bent over the cell phone for 77 hours a month: the damage is paid by the neck

How much time do we spend with the mobile in our hands? Surely too much and now it is also a research of the Mobile b2c Strategy Observatory of the School of Management of the Politecnico di Milano which shows that on average the hours on the mobile phone have risen to 77 hours per month (+ 29% compared to December 2019), equal to 83% of the time spent surfing the internet.
