"Nobody expects to trust his body overmuch after the age of fifty"

In this quote, Alexander Hamilton is revealing the typical belief that as individuals age, they end up being less reliant on their physical abilities. He recommends that as soon as someone reaches the age of fifty, they should not expect to fully trust their body. This could be due to the natural decline in physical strength and dexterity that typically comes with age. Hamilton might also be mentioning the idea that as people grow older, they end up being more knowledgeable about their own death and the constraints of their body. Overall, this quote highlights the social expectation that older individuals need to not rely too heavily on their physical capabilities.
