I quote from today`s on line Bucks Herald, “A drink driver who admitted
being more than four times over the limit is featured in this week’s round-up
from Aylesbury Magistrates Court. BRIDGET
LUMB, 46, of Fairford Leys Way, Aylesbury. On March 27 drove a Peugeot 3008 in
Aylesbury after consuming 161 microgrammes of alcohol in 100 millilitres of
breath (legal limit is 35mgs). Pleaded guilty. Awaiting sentence”.
It dawned on me reading that report that many
factors affect the absorption of alcohol into the bloodstream of the human body
and one of the most fundamental is a person`s weight. There is no detail of course on the above
reported woman`s weight but if a male Olympic heavyweight wrestler had consumed the
same amount of alcohol as that offender it is almost a given that his alcohol
level would have been lower than she exhibited.
Now the law in some circumstances has to be precise, sometimes so
precise as to be “strict liability”. Obesity, eg has changed in meaning over the last few years from a subjective
assessment of being overweight to a precise mathematical formula ;
The body mass index is calculated based on the following
formula:
Bodyweight in kilograms divided by height in meters squared
or
BMI = x KG / (y M * y M)
or
BMI = x KG / (y M * y M)
Where:
x=bodyweight in KG
y=height in m
y=height in m
Example for 175 cm height und 70 kg weight:
BMI = 70 / (1.75 * 1.75) = 22.86
The result is in kilograms by meters
squared, or KG/M2.
Exceeding the recommended limit opens the
door to medical intervention. Is it
beyond the wit of man or lawmakers to devise a more realistic evaluation of how
alcohol affects an individual`s ability to drive? My opinion has long been that the acceptable
level of alcohol should be zero but in the real world that is unlikely to be
adopted as the standard. Although there
are some practical objections foreseeable surely a more objective and fair test than
current limits would be more acceptable than the current one size
fits all.
