Re: "How incessant and great are the ills with which a prolonged old age is replete"
Not a bad attempt at all. Note that I deleted one of your verbs above. I have also added a word. "Ills" generally specifically refers to health issues although it can be used to simply mean "problems". You hear the phrase "The ills of the world ..." meaning "All the problems facing the planet ..."
