The spirit may be willing but the flesh may really compromise the success of your climb.
Though you may prepare yourself mentally & physically, there's no denying the medical facts which may spell disaster even before the start of the expedition :
- serious heart & lung diseases like emphysema
- serious brain / middle ear conditions like stroke & imbalance
- certain muscle / nerve disorders like myasthenia gravis
- old orthopedic injuries to the spine & major joints
- poor vision & other visual disabilities
