I'm really quite happy to say that in my early 40s, I wake up feeling sexy, and I can't say I felt that way in my late 20s.
And for yourself, whatever there has been either of sin or duty, remember the one and forget the other, and betake yourself wholly to the mercy of God and the merit of Christ.
That's basically what I'm doing when I'm tapping them - getting my toes to the end of my shoes.
