Most of the people in the world are going to age. And it is good news to spend more time on the planet, but, being so, we will also have to face natural challenges such as loss of mobility, physical strength, memory, sight, hearing, as well as the appearance of diseases that, at some point, they will be disabling. If these conditions were not severe, we could continue to be productive people and bring benefits to society, but no one knows how many opportunities there will be.
At the beginning of this century, mental health specialists in various countries predicted that, by 2020, depression would be the second cause of disability in the population. This prediction was fulfilled and exceeded as it was one of the consequences of the recent pandemic. In total, every 40 seconds, a person takes their own life somewhere in the world.
For many years, diseases such as scarlet fever, meningitis or measles caused collateral damage such as blindness or hearing loss to those who survived these and other viral or bacteriological infections. Unfortunately they are not always the only consequence, physical and mental damage are sometimes more than two in the same person.
