Young men may die, but old men must die.
Prov. Young people may be killed by accidents or disease, but old people cannot avoid dying for very long, simply because they are old. When Grandfather was so sick, he told us, "Don't feel too bad if I pass on; it's my time. Young men may die, old men must die." I'm afraid old Mr. Ferris won't live much longer. Young men may die, but old men must die.
