It's oddly common to see otherwise healthy old people suddenly deteriorate rapidly once their spouse, or some other significant person in their life, dies. The grief puts a lot of strain on an already strained-by-age heart, their mental faculties may slow down alongside that too due to their thoughts being so clouded by the death of their life long love. This in turn keeps them from making healthy choices, they may drink more, or they may not get out of bed which is VERY bad for extremely old people as they need all the movement and exercise they can muster. They may refuse help, seeking to be alone. And so on, and so on, and so forth.
There are probably other very real and physical things that happen in the body as a result of the cascade of emotions and trauma, too. Our brains are incredibly influential on our medical well being, and if it's not feeling good, we aren't feeling good either.
