One has to come to a personal decision based on accumulated risk factors.
Dehydration, Inactivity, Weight, Medication, diet, smoking, etc.
I reckon I'm high risk. My cornea has torn twice from dehydration, I don't really move when I'm working and I sleep too much. If I took spironolactone , which is a diruetic so i'd potentially get more dry, and then oral estrogens? I'd be so dead.
