Being Angry All the Time Will Hurts Heart

Everybody got experience being angry right? It's common to human nature, but beware, being angry all the time is not good for your health, and may cause you to death if it is unstoppable. A new report shows that having a short fuse may shorten the path to heart disease in men with prehypertension (blood pressure above normal but less than the high blood pressure range). So the researchers, who work at the Medical University of South Carolina, reason that those men may do their hearts a favor by learning to tame their chronic anger.

The same might be true of women, but it's going to take further studies to be certain of that. Meanwhile, there's no downside to healthy anger management. Data came from 2,334 U.S. adults aged 48-67. They were followed for four to eight years during the 1990s.

Compared with less angry men, chronically angry men with prehypertension were moderately more likely to develop high blood pressure (hypertension) and heart disease during the study. The same wasn't true of women, perhaps because few women developed heart disease during the study, note Marty Player, MD, colleagues.

For men and women alike, long-term psychological stress was linked to heart disease.

The results didn't change when the researchers factored in participants' age, sex, race, smoking status, and LDL ("bad") cholesterol. However, Player's team couldn't control for every conceivable risk factor for heart disease.

NASA spacecraft finds 7 Mars caves

An orbiting spacecraft has found evidence of what look like seven caves on the slopes of a Martian volcano, the space agency NASA said on Friday. The Mars Odyssey spacecraft has sent back images of very dark, nearly circular features that appear to be openings to underground spaces.

"They are cooler than the surrounding surface in the day and warmer at night," said Glen Cushing of the U.S. Geological Survey's Astrogeology Team and Northern Arizona University.

"Their thermal behavior is not as steady as large caves on Earth that often maintain a fairly constant temperature, but it is consistent with these being deep holes in the ground."

The holes, which the researchers have nicknamed the "Seven Sisters," are at some of the highest altitudes on the planet, on a volcano named Arsia Mons near Mars' tallest mountain, the researchers report in the journal Geophysical Research Letters.

"Whether these are just deep vertical shafts or openings into spacious caverns, they are entries to the subsurface of Mars," said USGS researcher Tim Titus.

"Somewhere on Mars, caves might provide a protected niche for past or current life, or shelter for humans in the future."

But not these caves.

"These are at such extreme altitude, they are poor candidates either for use as human habitation or for having microbial life," Cushing said. "Even if life has ever existed on Mars, it may not have migrated to this height."
