i dont think you can tell by looking at anyone unless they are overweight and I believe the risks increase, and im sure the chances increase with age
couple of years ago, i went for an afternoon nap. 3o mins later i woke up thought little joe was sitting on me, couldn't breathe or hardly move, took me 10mins to be able to get down the stairs. misses rushed me to A&E. by that time i felt ok, they did some tests, next day let me go, days later i went to my GP, can't remember why, told her i was in hospital, she took my BP was over 200/xxx - cant remember what xxx was, and told me i would have to take meds for the rest of my life.
up til then i had hardly ever been ill, never needed to go to the doc...
