Positive changes

Since I learned I had high blood pressure back in mid-November, I’ve been making a concerted effort to get my health house in order. A couple decades of little to no exercise and not paying a whole lot of attention to what I eat (although I was probably the most conscientious denizen of FAR Manor even then, which isn’t saying much) finally caught up to me. Fortunately, I didn’t find it difficult to do the things I have to, perhaps because I intended to (eventually) do them anyway.

Just as the years up to that point took their toll, the weeks since then are now starting to show results. I’ve lost 14 pounds (233 to 219 so far) — although I’m still trying to figure out where they came from in the first place. But weight isn’t the important thing. It’s too easy to focus on weight, especially since exercise often replaces fat weight with muscle weight; it’s just that it’s a convenient metric as easy to see as stepping on the scales. IMHO, obsessing about weight probably kills more diets than anything else… with the possible exception of assuming the whole thing is going to be an exercise in misery from the get-go.

Science Has Decreed: Laughter Counts as Exercise!, contributed by DuctapeFatwa

This will delight many of us here, including myself. I had long suspected that my being so easily amused is a benefit I had received for a reason, and this hunch has now been validated. Also, arithmetic is bad for you, another fact I have always instinctively known:

Watching comedy films boosts blood flow to the heart, finds a small study in the journal Heart.

Examples of sad films included the opening scene of Saving Private Ryan and examples of comedy films included There’s Something About Mary.

Participants were asked to abstain from drinking alcohol, using vitamins or herbs, or taking aerobic exercise the evening before the experiment, as all these can affect blood flow.

In all, 160 measurements of brachial artery blood flow were taken before and one minute after phases of laughter or sadness. The brachial artery runs from the shoulder to the elbow, and is a good indicator of blood flow around the body.

Brachial artery blood flow was reduced in 14 of the 20 participants after watching movie clips that caused distress. But it was increased in 19 of the 20 participants after watching movie clips that elicited laughter. The difference in flow between sad and happy responses exceeded 50 per cent.

The extent of the impact of watching a sad film was of the same magnitude as remembering episodes of anger and doing mental arithmetic, say the authors, while the impact of watching a funny film was equivalent to a bout of aerobic exercise or starting on statin treatment….
