Question of the Weak?

What is up with the older couple resting in the bathtubs in these commercials?

I am wondering if anyone knows what is up with the older couple resting in the bathtubs at the beginning and end of the these commercials. I understand them resting, watching a sunset, but why are they sitting in separate abstinence inducing (defeating the pills purpose I would think) bathtubs rather then a beach chair or something? Why not in a gazebo or a hot tub as opposed to a regular tub?

The only people that keep major appliances outside do not appear to be the target market for the product.
