cholesterol can be good and bad depending on the point your looking at it.
depending on the cholesterol it can be good and bad. your HDL and LDL must go hand in hand if you have to much LDL and not enough HDL then it can really effect you.
if you have to much HDL then you have to much low cholesterol.
HDL cleans up LDL
