At 73 years of age, John Wesley related in his journal (June 28, 1776) that he was far more able to preach than when 23-years-old; he traveled more than 4,000 miles a year (giving him exercise and "change of air"), made a practice of getting up at four in the morning, was able to go to sleep immediately, in his entire life never lost a night's sleep, experienced four illnesses that were used to invigorate him, and then he wrote about possessing what he called "evenness of temper": "I feel and grieve; but, by the grace of God, I fret at nothing."
