Mazeh Mei Chatas Discussion
1:36 AM yoel: btw - is it just my am haratzus that until I just learned daf 14 in Yuma today (of course I could have saved time by learning Rashi) - I assumed that the mazeh becomes Tamei? don't many meforshim seem to imply that - or have I just been "taitching" wrong my whole life...

A Chat on Tzimtzum
...what is the Rambam's shita on guf that one might construe as at odds with tzimtzum?
A Very Difficult IDL Psak: Feedback Welcome!
Dear Rabbi Bechhofer,
My response:
This is a weighty question, and I certainly do not want you to feel bound by my psak - feel free to consult another Rav and follow their psak.
My starting point is the psak of the Chazon Ish on the halachic International Dateline. Accordingly, the day of the week known in NZ as Sunday is actually Saturday. The day they call Saturday is actually Friday. The day they will keep as Tisha b'Av is actually the 8th day of Av, and the actual 9th is their tenth. This is a particular problem this year, since 9 Av is on a Thursday - but if you follow the CI, it's on the NZ Friday.
So, what I would pasken is that you keep two days Shabbos every week, on their Shabbos keep Shabbos d'orysa and d'rabbanan and daven tefillos Shabbos (because of Minhag HaMakom).
On Sunday refrain from all d'orysa's. You may ask anyone to do melachah for you on their Sunday, since they have al me lismoch for their manner of observance. On Sundays you should also refrain from d'Rabbanans as much as possible. If you must do one, try to do it with a shinui.
On their 9 Av, keep the day as normal. On their 10 Av, if you can, eat pachos pachos me'k'shiur (we can get into details if you decide to go this route) and all the halachos of the nine days until Chatzos. After Chatzos, you can shower and shave l'kovod Shabbos.
Again, feel free to contact anyone else you want. I will also see if I can come up with more guidelines.
Have fun!
KT,

SUNDAY, July 5 (HealthDay News) -- The growing evidence that caffeine consumption may help treat or prevent Alzheimer's disease has received an extra boost from two new studies.
Florida researchers report that a daily dose of 500 milligrams of caffeine -- the equivalent found in five 8-ounce cups of coffee -- reversed memory issues in mice bred to develop Alzheimer-like symptoms. After two months on the stimulant, the mice rebounded to score just as well on memory tests as normal mice of the same age that had never exhibited signs of dementia.
The studies, published in the July 5 online edition of the Journal of Alzheimer's Disease, also found that caffeine cut by half the mice's excessive blood and brain levels of beta amyloid, the protein linked to characteristic plaque found in human Alzheimer's disease.
"The new findings provide evidence that caffeine could be a viable 'treatment' for established Alzheimer's disease, and not simply a protective strategy," lead author Gary Arendash, a University of South Florida neuroscientist, said in a news release. "That's important because caffeine is a safe drug for most people, it easily enters the brain, and it appears to directly affect the disease process."
Past work at the Florida Alzheimer's Disease Research Center in Tampa, where these studies were done, found that caffeine in early adulthood appeared to prevent memory problems from occurring in these specially bred mice, possibly because of the stimulant's ability to calm the brain inflammation that causes beta amyloid levels to rise.
The research center also previously found that caffeine reduces beta amyloid levels in elderly people without dementia just as quickly as it does in the mice bred to have Alzheimer's symptoms.
Studies to test whether caffeine can help people with mild cognitive impairment or early Alzheimer's disease are likely to follow, investigator Huntington Potter, director of the Florida Alzheimer's Disease Research Center, said in the news release.
While consuming 500 milligrams of caffeine a day would not cause ill effects for most people, Arendash noted that people with high blood pressure or who are pregnant need to limit their caffeine intake. It is not known whether a smaller daily dose of caffeine would produce the same beneficial effects on the Alzheimer's mice.
In the most recent experiments, the researchers also found that caffeine did not improve the memory of normal mice as it did for the Alzheimer's mice. "This suggests that caffeine will not increase memory performance above normal levels. Rather, it appears to benefit those destined to develop Alzheimer's disease," Arendash said.
