'All the Days of His Life' in the Bible

This is what I have seen: it is good and fair for a man to take meat and drink and to have joy in all his work under the sun, all the days of his life which God has given him; that is his reward.

So I gave praise to joy, because there is nothing better for a man to do under the sun than to take meat and drink and be happy; for that will be with him in his work all the days of his life which God gives him under the sun.
