Over 65 is not old anymore, old age is a thing of the past, just like bad engines don’t exist. With careful maintenance and a few glasses of wine you can do anything.
My friend and I drank a litre and a half of wine during our 20 kilometres hike in the mountains. Without it the walk would not have been the same. Next time we are camping, that way we can drink 2 litres.
