A column today in the Telegraph, PDF attached.
In a similar vein, although no stats to support this but I wonder just how much of the surge in dementia, Alzheimer's etc is caused by alcohol and drugs. If someone has medication for depression to help them forget, they can hardly be surprised if eventually they don't remember everything.
I know nothing about the US but until 40 plus years ago in Britain the majority of drinking was once or twice a week in a pub. There was little at-home drinking, which is popular today. At home it is easy to drink far more than you would in a pub. Also, back then your doctor would tend to attempt a cure of the cause, rather than treat the symptoms. Not that I care because I stopped drinking eight years ago and don't even take paracetamol. I have sciatica but just try to ignore the pain, particularly so when I see the admitted side effects on the drug solutions on offer.
Another thought of mine is coffee. Back in the 70s a friend who was a nurse came back from Canada where she took part in post-mortems. Then in the UK we drank little coffee. She was surprised just how black the insides were of the coffee drinking Canadians. In fact, if you don't wash a coffee cup well, it will eventually stain, which will be near impossible to remove. You have to think that it must be the same inside a coffee drinker. Can, or does it get into your veins? I don't know. Not that I worry about coffee, or tea, as neither my wife or myself have had any for fifty years or so.
