How would a 20 bal effect a 160 lb man?

A 20 BAL (Blood Alcohol Level) would have severe and potentially life-threatening effects on a 160 lb man. At this level, the individual would likely experience extreme impairment of motor skills, loss of consciousness, and a high risk of respiratory failure. It could also lead to alcohol poisoning, which may require immediate medical intervention. Such a BAL is well above the legal limit for driving and poses serious health risks.
