I went to bed pretty sure that someone was going to do that. You're right. I only have a -17° stem. Quite ordinary. But I do think that a few inches drop is better for one's back than a more upright posture, though many preach the opposite. Folks I ride with agree with me. Pilates and plenty of drop seems to be the recipe that works for most. If one continues to ride and work out, age doesn't seem to matter as long as one avoids serious back injury.
