Measure your health by your sympathy with morning and spring. If there is no response in you to the awakening of nature -if the prospect of an early morning walk does not banish sleep, if the warble of the first bluebird does not thrill you -know that the morning and spring of your life are past. Thus may you feel your pulse.
