Our Amazing Body – nails and hair

August 11th, 2016 Comments off

Fingernails grow nearly 4 times faster than toenails. If you notice that you’re trimming your fingernails much more frequently than your toenails you’re not just imagining it. The nails that get the most exposure and are used most frequently grow the fastest. On average, nails on both the toes and fingers grow about one-tenth of an inch each month.

The lifespan of a human hair is 3 to 7 years on average. While you quite a few hairs each day, your hairs actually have a pretty long life providing they aren’t subject to any trauma. Your hairs will likely get to see several different haircuts, styles, and even possibly decades before they fall out on their own.

You must lose over 50% of your scalp hairs before it is apparent to anyone. You lose hundreds of hairs a day but you’ll have to lose a lot more before you or anyone else will notice. Half of the hairs on your pretty little head will have to disappear before your impending baldness will become obvious to all those around you.

Human hair is virtually indestructible. Aside from it’s flammability, human hair decays at such a slow rate that it is practically non-disintegrative. If you’ve ever wondered how your how clogs up your pipes so quick consider this: hair cannot be destroyed by cold, change of climate, water, or other natural forces and it is resistant to many kinds of acids and corrosive chemicals.

 

Votes for Women

Why did women (mothers, grandmothers, wives, sisters, cousins, nieces, friends) have to work so hard to get the vote?  Were men afraid we would take over, or that we would make poor decisions?  Why did we have to beg for our rights?  I’ve never understood.  Could we possibly have done worse than the men?  

In this photo a few brave men joined in the cause.  Were they husbands or activists?  The guy in the middle seem to be a bit braver perhaps than those in the back, but they were there nevertheless, posing for a picture than we are looking at today, almost a hundred years later.

Do we as women still have all the rights that we deserve -equal pay, equal promotion opportunities, equal respect, equal representation?  You know the answer.

Underwater Photographer Randy Harwood – The Coral Grouper

Coral Grouper, Cephalopholis Miniata  Photographed at Peleliu, Palau, Micronesia by Randy Harwood 

This stunning creature is often seen peering from under a coral colony or moving from one ambush site to another.

The festive red and blue coloration of the coral grouper belies a voracious appetite. Its diet consists mainly of small reef fishes, including the ubiquitous scalefin anthias. It relies on stealth to get close to its quarry. When within striking distance, it will explode into the water column to intercept an individual anthias before it can rush back to cover.

The coral grouper tends to do most of its hunting during dawn and dusk – it is known as a crepuscular predator. In some cases it will follow morays or octopuses as they probe reef cracks and crevices looking for food. The hunting activity of these predators will sometimes flush food from cover that the coral grouper than snaps up.

Juveniles of this species have fewer, less conspicuous spots than the adults.
