Mountain climbing stiffie?

Viagra protects mountain climbers lungs

The researchers used climbers as “guinea pigs” to test how effective Viagra was in relieving pulmonary hypertension. :confused:

Fourteen healthy male mountaineers were given either Viagra (sildenafil) or a dummy pill.

It was found sildenafil reduced high blood pressure and improved the transport of oxygen in the blood in both situations.:dubious:

Sildenafil is used because there is a biochemical similarity between the penis and the lungs :eek:

Climb every mountain, erect penis in tow
Follow every byway, ready for a blow.
Climb every mountain, Johnson pointing up-stream,
Follow every rainbow, hung like in your dream!

Lieu, that’s the second time this week you made me laugh out loud. Thank you.
