Might be more informative to see a table on risk analysis compared to other 'vices' or life activities.

ie:-
Smoking
Diet
Sports
Living in the inner city
Exposure to air pollution etc

Our world is a hazardous place to live.
Our individual lives incur multiple risks 24/7
All these risks can be quantified. Some may be eliminated but this just move others up the "risk-table"

Looking back in time we see that life expectancy has increased significantly. Does this mean that the sum of all the risks we are exposed to has decreased ?

If you're lucky enough to wake up after sleeping do you drink coffee? or tea?
Sugar or sweetner?
Or do you abstain and drink water instead? Is it chlorinated? That's a risk too.

How do you get to work? Walking, bicycle, bus or car ? all have associated risks.

Do you travel by air from time-to-time ? What's the risk of comic radiation exposure at 30,000 feet? Is it 40 time that at sea level? Are you bothered?

Maybe there's an amount of alcohol we can consume where the risk is zero but the 'scientists' can't measure that low, so it's easier to assume that every drink contributes to the total risk.
Sorry, doesn't make sense to me.

Excessive alcohol consumption MAY cause cirrhosis of the liver.
Moderate consumption MAY promote relaxation and reduce stress to give a good nights sleep. Maybe the positives of this outweigh the negatives ?

Whats the risk comparison?

I've now reached state pension age. What is risk to my life if I continue to drink alcohol compared to if I quit ?

Part of my job as a Railway Engineer on safety critical components was risk evaluation in failure mode and effects analysis

I've pretty much forgotten all that stuff and I'd imagine it's gotten much simpler now with technology and much smarter computers.

This post is just another of my ponderings. (ramblings if you prefer)

Justification if you like that I'll not be changing my habits when it comes to enjoying my beer
