Fish delivery and more
It is not great because of New Year. I have some Japanese fish but they are farm raised. Good fish are coming on Thursday. I received good tuna yesterday. This big eye tuna was not bad but the size was not big like last time. It was only 37 lbs (The last one was 52 lbs.) Uni is available. CA storm was over and can get delivery from there.
My Weight Control and Golf
I am struggling about weight control. It never been over 170 lbs. But it is around 169 lbs. This is not fun for me. I was looking for 165 lbs 4 weeks ago and did not reach at all. I am thinking to get sweat this time and need to find more active workout. I think I need to run. But I don’t have much power to run. By the way, my golf game is really good. I play around 85 and never lose money.
A new U.S. study suggests drinking three or more cups of caffeinated coffee a day increases the risk of vision loss or blindness.
On the other hand, researchers found regular pop, tea, chocolate or decaffeinated coffee didn't have an impact on sight.
The study looked at two American cohorts, nearly 79,000 women and more than 41,000 men, all over the age of 40. They answered questionnaires about how much java they drink, and researchers looked at their medical records for exfoliation glaucoma — which causes increased eye pressure that could damage the optic nerve and lead to vision loss.
Heavy caffeinated coffee drinkers were found to be at greater risk of developing exfoliation glaucoma than those who don't drink coffee. Researchers found women with a history of the condition have an increased risk.
Dr. Jae Hee Kang, the study's author based at the Brigham and Women's Hospital in Boston, Mass., said Scandinavian residents have the highest rates of glaucoma in the world and also drink the most caffeinated coffee. In a previous study, they linked heavy coffee intake with an increased risk of primary open-angle glaucoma.
Kang said further study in more places around the world is needed.
"Because this is the first study to evaluate the association between caffeinated coffee and exfoliation glaucoma in a U.S. population, confirmation of these results in other populations would be needed to lend more credence to the possibility that caffeinated coffee might be a modifiable risk factor for glaucoma," Kang said.
The study was published Thursday in the Investigative Ophthalmology & Visual Science journal.
