It is also depending on how you lived. My grandmother is 97. Mental health is 100% good. Body is slowly failing but she is not sick of any chronic illness. Just some weak kidneys that need to be boosted by supplements. As opposed to her, my mom is 71, with at least 3-4 chronic diseases and 24 pils to take daily. Me, close to 50, I start to be at risk of the same chronic diseases like my parents.
