sorry, there is a misunderstanding, my remark about life worth living, was not applying to myself,[although I agree,I should have phrased it better,]it was a reference to isolated dwellers,,whose main social activity might be once a week in a local pub.
I do not fall into that category   I can walk to my local pub[it is about one mile], and frequently do, weather permitting.
however there will not be many pubs left in rural ireland to walk to soon,they seem to be closing rapidly.
yes, but faster reactions are no use, when you are going 70 100 mph. the faster the speed the greater the braking distance required [check Rowans post].
sorry, but a driver going 30 to 35 mph[imo]having consumed two pints lets say in two and a half or three hours,is less dangerous than a driver going 65 70 80 mph plus who is perfectly sober and breaking the speed limit.
can you provide statistics otherwise.
