Moderately overweight elderly people may live longer than those of normal weight, an Australian study suggests, but being very overweight or being underweight shortened lives.
The study of 9,200 over-70s found that regardless of weight, sedentary lifestyles shortened lives, particularly for women. The report, published in the Journal of the American Geriatric Society, said dieting may not be beneficial in this age group.
The team tracked the number of deaths over 10 years among volunteers who were aged 70 - 75 at the start of the study. It found that those with a BMI which classed them as overweight not only had the lowest overall risk of dying, they also had the lowest risk of dying from specific diseases, such as cardiovascular disease, cancer, and chronic respiratory disease.
Overall death rate among the obese group was similar to that among those of normal weight, but those who were very obese had a greater risk of dying during the 10 year period.
The conclusion of this study is that being overweight may be less harmful for elderly people and it corroborates the findings of previous research.
However, sedentary lifestyles shortened lives across all weight groups, doubling the risk of mortality for women over the period studied, and increasing it by 25% for men. I think I need to go fix a bacon, bacon, bacon and cheese sandwich with potato chips on the side.

Health and Wealth
Whether you think health or wealth is more important depends upon which one you have lost.
Popeye's Chicken
Did you know the name came from Popeye Doyle, from The French Connection, not Popeye the Sailor Man. Now you do.
Google Buzz
This week Google announced Buzz. It is the Google answer to Facebook and it is incorporated right in Gmail. If you have a Gmail (free) email address check it out by clicking on Buzz on the left side of the page. Very easy to add comments, pics, videos, etc. Easier than Facebook. I'm buzzed about this.

Rainbows
A rainbow is not the flat two-dimensional arc it appears to be. It appears flat for the same reason a spherical burst of fireworks high in the sky appears as a disk-because of a
lack of distance cues. The rainbow you see is actually a three-dimensional cone with the tip at your eye.
Consider a glass cone, the shape of those paper cones you sometimes see at drinking fountains. If you held the tip of such a glass cone against your eye, you would see the glass as a circle. All the drops that disperse the rainbow's light toward you lie in the shape of a cone of different layers with drops that deflect red to your eye on the outside, orange beneath the red, yellow beneath the orange, and so on all the way to violet on the inner conical surface. The thicker the region containing the water drops, the thicker conical edge that you look through.
Your cone of vision that intersects the cloud of drops that creates your rainbow is different from that of a person next to you. Everybody sees his or her own personal rainbow.
If the Earth were not in the way, a rainbow would be a complete circle. This is why you will never find the golden pot at the end of the rainbow.

Swan Song
A final gesture or performance, given before dying. This term derived from the legend that, while they are mute during the rest of their lives, swans sing beautifully and mournfully just before they die. This isn't actually true, swans have a variety of vocal sounds and they don't sing before they die. The legend was known to be false as early as the days of ancient Rome, when Pliny the Elder refuted it in Natural History, AD 77: "Observation shows that the story that the dying swan sings is false."
Poetic imagery proved to be more attractive than science and many poets and playwrights made use of the fable. Shakespeare even used the image in The Merchant of Venice. Portia: "Let music sound while he doth make his choice; then, if he lose, he makes a swan-like end, fading in music."
The actual term 'swan song', seems to have begun in print in the 18th century. The Scottish cleric Jon Willison used the expression in one of his Scripture Songs, 1767, where he refers to "King David's swan-song".
Samuel Taylor Coleridge turned this around in the poem 'On a Volunteer Singer'.
Swans sing before they die; ’twere no bad thing
Did certain persons die before they sing.
Swan-song is now commonly used to refer to performers embarking on farewell tours or final performances.

Ikea
Each year, Ikea sends out 180 million catalogs. That means there are more of them printed annually than bibles.
