Health without money is half an ague. [ English Proverb, collected by George Herbert ]

By fits and girts, as an ague takes a goose. [ Proverb ]

Love that has nothing but beauty to keep it in good health is short-lived, and apt to have ague fits. [ Erasmus ]

Grief! thou art classed amongst the depressing passions. And true it is that thou humblest to the dust, but also thou exaltest to the clouds. Thou shakest us with ague, but also thou steadiest like frost. Thou sickenest the heart, but also thou healest its infirmities. [ De Quincey ]

Irresolution is a worse vice than rashness. He that shoots best may sometimes miss the mark; but he that shoots not at all can never hit it. Irresolution loosens all the joints of a state; like an ague, it shakes not this nor that limb, but all the body is at once in a fit. The irresolute man is lifted from one place to another; so hatcheth nothing, but addles all his actions. [ Feltham ]
