I recently heard/sung "Here Is Love," a hymn that has twomelodies and, I think, was originally Welsh. It was definitely part of the Welsh revival at the beginning of the 20th century. Huw Priday sings a verse in Welsh and then the rest in English in this video. Let your spirit soar.
Elihu, in Job 32:7, had a good thought: "I thought, 'Age should speak; advanced years should teach wisdom.'"
According to recent research, as reported by ScienceDaily, wisdom truly is an advantage gained by age. Notice the first sentence of the second paragraph--it gives the definition of wisdom in the study. Wisdom here is basically experience. That is not a bad definition, though wisdom is a difficult word to pin down. And biblical wisdom is certainly more than mere experience.
