    Interesting article from New Scientist on physical fitness.

    http://www.newscientist.com/article/...t-fitness.html

    Some of the points made :

    Minimum recommended amount of exercise is 150 minutes per week, of moderate-intensity exercise. Moderate intensity could be anything from brisk walking, brisk housework (like vacuuming), or even the more strenuous activities in gardening. It appears that how you divide up that 150 minutes is of minimal importance. Whether you do 22 minutes each day, or twice a week sessions of 75 minutes, you achieve the fitness goal either way.

    Aerobic fitness is most important, in which the heart gets better at pumping blood, and the lungs better at gas exchange.

    Strength increasing exercises, like pumping iron, are important. If your muscle tone gets less, so do your chances of surviving to a good age.

    Exercise increases probability of no heart attacks. The risk of the stress of jogging bringing on a heart attack is way less than the benefit to the heart.

    Fat people can be fit. Indeed, a person who is overweight or even a bit obese, who nevertheless keeps fit, will live longer than a person who is skinny and out of condition. In fact, a fit and fat person seems to be as healthy as a fit and normal weight person.

    Pushing fluids is of no benefit. You need to drink enough to quench thirst, but any extra is more likely to harm than help.

    It's good to know that gardening can provide some level of fitness too aside from gym workouts. I spend a lot of time digging in my garden every Spring and it's amazing how exhausting that can be! I've been trying to get a decent garden going for the last few years but I guess I just haven't been using enough fertilizer because although I can get some great herb plants growing I can't seem to get too much happening in the way of vegetables. I'll have to spend more time researching what the problem may be.

    That's interesting too that you can be fat and still be fit because that's not something I would have thought reasonable. It always seemed to me that if you're overweight then by definition you aren't getting enough exercise and so you aren't fit. Well, you learn something new every day. Thanks for the info!

    Cheers tr.

    Just to add another point from the article. It scotches another myth. It appears that, while sex is good for us on lots of levels, it is actually rather a poor exercise, at least in terms of energy expenditure.

    The article places sex as equivalent to slow walking. Which is not a recommended exercise, compared to brisk walking.

    Try running a mineral/ pH test. herbs are less sensitive to pH and such. Also i usually only grow on a specific spot every other year. I put lots of compost in it the year i don't grow. it works for me. cucumber plants that grow larger than me hah hah im 5'6".

    Well i don't think i necessarily agree with the idea that an obese fit person can be healthier than a skinny(but not emaciated) unfit person. I assume that by skinny you mean body fat% not just how big someone is. Because larger people tend to have a greater strain on the heart. more weight to carry around harder it works. not to mention diabetes, bp, joint problems.

    My premise is on the idea that obesity has nothing to do with size, but with fat%.
    Nothing is certain, but uncertainty.

    I know of several nonagenarians who have never felt the need to work out or diet in their lives. What they have in common is energy, a good brain and a moderate lifestyle and diet. Having good people around them probably also helps. I know of one 95 year old who is still working every day. The problem with exercise is that it can take too much energy out of your body. This may not be a problem for the under 30's, but once you get over 50 maybe it's better not to start running marathons.

    There was a recent article in New Scientist journal on longevity. It ascribes very long life to genetics.

    Each of us has a potential life span that depends on our genes. How close we get to our maximum potential depends on other factors such as diet, exercise, managing stress etc. However, if we got the wrong genes we are not gonna live to a great age.

    That's exactly what I was implying, without mentioning genetics. Don't expect to be healthy just because you exercise a lot. My idea for 10 health commandments are:
    Thou shalt...
    * Not smoke (at all).
    * Not drink alcohol to excess (better to drink water than wine).
    * Keep within the recommended daily nutritional guidelines (< 70 grams fat, < 6 grams salt, < 90 grams sugar).
    * Eat at least 5 portions of fruit and veg. a day.
    * Think about how little you can eat, not how much.
    * Walk or cycle for short journeys.
    * Not take the lift, but walk up stairs.
    * Get checked out regularly for blood pressure, cholesterol, blood sugar, thyroid, prostate etc.
    * Not go to the expensive gym, but buy walking boots, joggers and a bicycle (it's better to exercise outdoors).
    * Enjoy life while you can, and help others.

    There are other 'commandments' also. Recent research has shown how important social factors are in achieving health and long life. So you can add to your list :

    Get married and make sure it is a good, loving marriage of mutual support. (A bad marriage reduces longevity). I could write a book on the techniques you use to make your marriage happy, at least from the husband's view point.

    Work on your social relationships. If you have warm and friendly and frequent contact with friends, family and neighbors, it increases health and life span.

    Manage stress well. Zero stress is not good since boredom reduces life span. But bad stress is probably worse. So keep your life exciting, but don't get over stressed.

    Exercise needs to be regular - at least 150 minutes per week, and needs to be varied. I am not sure I agree with you that it needs to be outdoors. Indoors in a gym is fine. You need to carry out exercises that increase flexibility, that strengthen your back muscles, that strengthen arm and leg muscles (like pumping iron), that strengthen heart and lungs (aerobic), and sometimes specialised exercises for special needs. For example, I juggle to maintain coordination, and I do a balancing exercise to avoid the 'falling down' so common to people growing older. My 'special' need is that I am now 61 and I want to avoid the loss of balance and coordination that ageing brings.

    I would also de-emphasize your prohibition on alcohol. While excessive drinking is, indeed, bad, moderate drinking carries some very positive virtues. It 'lubricates' those very valuable social contacts. It reduces that bad stress - I know - so does exercise, but I am suggesting both. And if your choose the correct alcoholic drink, it may contain valuable nutrients. eg. Red wine.

    As I understand, the number of happy marriages runs at < 10%, while the number of happy divorces is clearly 100%. Nobody is a winner in life, because ultimately we're all losers. Happy relationships always end sooner or later, so it's better not to place too much reliance on them. All meetings end in separation (Buddha).
    When a partner dies, the other is often left devastated, resulting in a downward spiral, and then health crazes are of no use to the soul.
    Alternatively, get used to solitude, and realise that it has a bliss all of its own.

    I understand your logic, but it is flawed.

    The statement that good, loving marriages lead to longer life is not an opinion. It is the result of empirical studies. Even though (usually) one partner dies well before the other, the surviving partner will still live a longer life than if he/she had never married. This statement is statistically true, though, of course, it cannot be applied to each and every individual.

    It is however entirely possible that healthy individuals are more likely to enjoy healthy marriages.

    That's interesting. I wonder if the same applies if a person is married say, 3 times and still out-lives all of his/her spouses? I'm sure that would be an interesting study to read. Thanks.

    I doubt it would apply to his/her spouses.

    I am a true believer in making fitness fun. I play tennis at least 3 times/week and I love it. I swim the other 3 days. I typically run or bike on days i can' swim. At 32, I'm in the best shape of my life. Everything from templates on MS office to the nike + make it fun to track your fitness routine. I go to www.vigorousliving.com and get lo carb meal replacements for breakfast. Weights 3 days a week. Wine whenever. If you set it up right, you feel terrible not to maintain your healthy lifestyle.
