Like most things, medicine has changed a lot throughout history too. What was thought to be healthy decades ago turned out to be super dangerous. If we think about it, even the definition of being healthy and living longer was different than we know it today.
Nowadays, being healthy implies a plethora of activities and lifestyle changes such as diet, exercising, and proper sleep. For most of us, it is pretty shocking to find out that mercury, for instance, was actually used as a treatment for syphilis. This is just an example, so arm yourself with patience because it’s going to be a long ride, just like the ice picks used for lobotomy.
