I did not know this:
…when it comes to cancer, there is no safe level of alcohol consumption.
There are other sources that appear to agree with this conclusion.
There have been times in the past when I would have a few ounces of red wine before going to bed on a regular basis. Recently I only occasionally have a sip of wine from the glass of Barb L. Hence my lifetime alcohol consumption is very low and now I can be even more self-righteous about it.
