The sympathetic nervous system is a part of the nervous system that controls heart rate and other involuntary body responses. Patients with heart disease sometimes have poor sympathetic function, the authors explain, but whether or not antioxidants can improve this complication remains unclear. Dr. Kazuyo Kato and colleagues from Nippon Medical School, Tokyo, investigated whether ascorbic acid influenced the sympathetic response to exercise in 21 men who were studied at least one month after a myocardial infarction. The participants underwent symptom-limited exercise testing twice, once 2 hours after oral administration of 2 grams of ascorbic acid and once without the supplement. Although resting blood pressure and heart rate did not differ with or without ascorbic acid, the authors report, the heart rate response to peak exercise was significantly higher, an indication of better heart function, after ascorbic acid than without ascorbic acid. Ascorbic acid administration also improved heart rate increases from rest to peak exercise, as well as the peak oxygen consumption, the results indicate. "These data suggest that an antioxidant vitamin such as ascorbic acid can effect a recovery of the sympathetic dysfunction caused by injury through excessive oxidative stress and improve exercise intolerance," Dr. Kato and colleagues conclude. "Further studies are needed to determine whether long-term ascorbic acid administration will improve sympathetic nerve dysfunction in patients and whether other antioxidants would have the same effects as ascorbic acid," the investigators add.

Vitamin C is the nutrient most likely to extend our lives, as large observational studies associate supplementation to a dramatic reduction in all-cause mortality. Think about the fact that almost every mammal on the planet synthesizes its own vitamin C, that our pets (not exposed to undue environmental stresses) live roughly x12 times their age at puberty. Most humans can live to be 120 years of age, if not for poor intake of nutrients combined with chemical exposures (ie., pharmaceutical drugs, pesticides, food additives.) In fact, vitamin C can greatly compensate for those exposures.

By golly, humans must be just about the unluckiest creatures on the planet. I mean, here PeterB tells us that most humans can live to be 120, if they play their cards right, and yet, despite that, there is only one well-documented case in all of human history of a person living to that age. (That being Jeanne Calment, who lived to be 122. There are many others who claimed to have made it to 120, but none of them could be documented, and in fact at any given time, the oldest known human is usually around 115 or 116. Very, very few people make it past 110.) Guess everyone else in history has had bad nutrition and chemical exposures. -- David Wright :: alphabeta at prodigy.net These are my opinions only, but they're almost always correct.

Read the text from Peter again, and you'll find: "...,there is only one well-documented case.." Read that - 'well-documented'. The article you cite clearly says the case was not well documented ("...but since it is not an official record, it cannot be used to authenticate the claim.") and that there was no scientific confirmation of her age whatsoever ("Unfotunately, her death came before the scientific community could confirm her age."). So Jan, will you admit you didn't read what Peter said correctly and/or did not read the article correctly? (I am feeling awfully optimistic today you know) >>Guess everyone else in history has had bad nutrition and chemical >>exposures. >> >> -- David Wright :: alphabeta at prodigy.net >> These are my opinions only, but they're almost always correct. >> I used to think that spammers should be hanged, but I've >> changed my mind.
