First time I heard the word cosmology I thought they were talking about a cosmologist.
My sister used to be one and worked in a beauty salon as a hairdresser back in the days when you could smell the peroxide and all the women would get their hair died blonde. Back in the early 1950s.
I had to bring her lunch from home and hated the smell. She eventually moved on to a job with Mellon Bank and then got a job with a school district and worked there until she retired.
Sadly, shortly after her 50th wedding anniversary her husband had a stroke and later developed Alzheimer's and recently died from complications from the disease. An Aunt of mine has also developed Alzheimer's.
Both he and my Aunt drank heavily and I think there's a tie in to that and Alzheimers but can't prove it. He had completely stopped drinking in later life. He mainly drank beer but don't know if that's a factor or not.
He used to build houses with his brothers and I used to help out when I was a kid. They're all gone now.
I do know that Sinatra drank hard liquor for years and when he turned 80 he could no longer remember lyrics or songs and cried over it.
I think eventually the stuff destroys brain cells. Alzheimer's is a horrible disease and I hope they find a cure or a vaccine for it one day.
