die co.ck stand is the same as chinese MA SHANG FONG......
means the same as you literally die while having s.e.x. with your
co.ck standing.... 
that happens to alot of people in their 60s+ in the early 80s to
90s. This occurs most probably because the old man took TOO MUCH
APPRODIACIAH...like tongkat ali etc... and also got high blood
pressure or something then when they do they get so high and just
when they reached climax, they die....
the reason why chinese called MA, is also because this is common
for the horses also...
