my name is dr charles when i conduct research in the field of physiology the story you are about to see involves some facts about physiology but it is more than a clinical report it is a story that revolves around two seemingly unrelated articles a good luck charm and an ordinary hyp you know it as alcohol my research is devoted to alcohol and its effects on the human body but not all experimenting is done in laboratory such as this  certain amount of experimentation goes on under less scientific condition because you like to plan everything in advance nothing for the moment and i have no i didn't say it was then just different for me i guess i like to let things take their course but you have their here in the laboratory we've devised some scientific method to determine what effect keith and jerry might reasonably expect from their haphazard experiments with alcohol we use test animals definite amounts of alcohol this animal has no alcohol in its system you might compare it to a ginger ale drinker this is an animal which has previously been injected with only and alcohol to bring the level in its blood to what it will be in a human being after drinking four beers the third edible has received and nothing alcohol to bring its blood alcohol level up to a percentage comparable to that of a heavy indulgence say someone who had been holding down the fort all evening watched the first one the one without alcohol his reflexes are fast and automatic he immediately copes with the unusual situation in number two with a moderate amount of alcohol coordination seems to take more effort he made the unexpected situation less skillfully there's a perceptible decrease in his ability to balance his reflexes are impaired now let's look at the third one well under the influence of alcohol he meets the situation in a completely befuddled state not the complete inability to balance this one is just not fit to cope with the situation yes he can walk away test animals aren't alone in showing these reactions let's take a walk over to a classroom where human reactions are being tested now let's see what would happen when driving under the influence of  to find out we use the driver trainer a unique teaching device with real car controls the driver trainer employers a series of special instructional films to present actual on the road driving conditions shown others the drivers of these individual classroom cars have a driver's i view this smoke and picture a highway let's imagine you're driving and haven't taken alcohol watch out for the delivery man your rapid perception of the situation and quick break reaction prevented what could have been a fatal accident now let's suppose you had done some drinking and are driving down the same road you were driving a little too fast and have a false sense of confidence why should i few more feet might have meant tragedy this time let's imagine you're fully under the influence reflexes are slow judgment poor and your too late and too slow to avoid hitting the delivery man your confidence was high but your reactions and judgment were low yes like animal number three here when you're under the influence of alcohol you keep on trying you keep on thinking you can your coordination is low but your confidence may be high certainly jerry landon's confidence was high gods and you ain't nothin yet jerry in front of an audience may be able to perform satisfactorily but when he's alone and driving he lets down and loses his concern and therefore the safety somewhere with this drunken driver was behind the wheel but by the time dad and bad had taken the other couple home they felt much less apprehensive they supposed keys had caught up with jerry in time and then the description fits jerry's car so i guess he's saying the police took him on and thank heaven for a minute there i thought it was  the way jerry was had he been the police might have picked him up too but keith had just enough alcohol to slow his reactions in a critical moment a moment that was to send him and mary and eighty to the hospital i know one thing you can't trust to luck if the driver's been drinking it's got to stick to your guns and turn down the ride  nobody can afford to drive with alcohol present in the body today's heavy traffic and high speed cars make the odds heavy against the non drinking driver out of consideration for the safety of others and yourself should you drive if you have been drinking recently should you ride with a driver who hands these decisions out not to be difficult for you to make
