...No, Tea honest.
I agree about the drink awareness thing... the course I attended over 4 sessions was perhaps the most useful driving related information I've ever been given. It informs you about the dangers of alcohol (most is obvious), but also gives you the knowledge to calculate your alcohol consumption and more importantly, whether you will or will not be above or below the legal limit... this is particularly useful for people that falsely believe they are fine to drink the morning after the night before... it is so useful it should form part of the driving test I believe.
the old tactic of police cars pulling you over at 15 minutes after closing time is a bit of an urban myth now... the vast majority of people these days are caught on their way to work between 7am and 9am... completely unaware that having consumed alcohol the night before that they may still be over the legal limit, the body only removes alcohol from the body via the liver at a constant rate of 1 unit per hour... and nothing you eat, nothing you drink, and no amount of exercise changes that constant rate.
Its a bit of an eye opener to suddenly realise that for years I'd probably been driving the morning after the night before and been legally over the limit, even if you just feel groggy and perfectly sober... you can still be well over...
if anybody doesn't know how to calculate it, you do the following sum:
ABV * Volume / 1000 = No Of Units
e.g.
If you drink 2 large glasses (250ml) of Red Wine with an ABV (Alcohol By Volume) of 14%... (read the wine label and it always states the % of alcohol content)...
so you calculate 14 * 500ml and divide by 1000...
the answer is 7 Units... in the UK an average MAN would fail a breath test at 5 units, and an average woman would fail the breath test at just 3 units...
The other important thing to understand is that the liver is the only organ in the body that will break alcohol down, and no amount of bread or milk beforehand will stop the alcohol you later consume from entering your bloodstream, if if goes in your mouth it will enter your bloodstream...
the Liver starts to break down alcohol after one hour and at the constant rate of one unit per hour... so assuming you went out for lunch at 1pm and had two large glasses of wine before heading back to work at 2pm ... you would not be legal to drive again until at least 7pm for a woman and 5pm for a man.
Now if like me, you've had the odd night where you've drunk perhaps 4-5 pints of strong beer followed by a curry and a couple of irish coffees, then got up early to play golf in the morning... you can see why the police have changed their tactics for targeting the morning driver...
in my example, in hindsight, I would have consumed perhaps 15 units... assuming I started drinking at 9pm and went to bed at 1am... by my calculation I would not have been legal to drive until at least 9am the next day... when the alcohol level in my body would have reduced to just 4 units... so driving at 7am in the morning even though I may have felt sober as a judge after 6 hours of sleep, I would have still had 6 units in my blood, and would have failed a breath test by some considerable margin... and received a minimum ban of at least 12 months...
... pretty sobering stuff... no pun intended!
