Oh. thanks for the info.  I need to fatten up my 13 year old then. Abs are showing.

Genetic tendencies play a role in children's body composition. Some are naturally quite lean and muscular. One of my sons was so lean - about 7% - that he couldn't be on the swim team in the winter because he'd turn blue and shiver during winter practices. He never developed a layer of subcutaneous fat like most swimmers do. He had a six-pack since childhood. At 35 today, he is still naturally lean. He is very active and athletic, so I won't say he gets his muscle definition without any effort, but his efforts are recreational only, not fitness-goal oriented.

Cool find.

When I ponder the question "What makes us human?" I personally believe that relentless invention of tools is foremost. My own observation is that children imitate tool usage well before they are one year of age, and start making their own purposeful tools before they are four or five.

I didn't see you mention this important point, and I hope you will forgive me if I'm offering unwanted advice.

In his book the Omivore's Dilemma, author/researcher Michael Pollen explains the difference between animal foods from naturally-fed livestock and livestock fed a species-inappropriate diet, (such as feeding corn and soybeans to beef).

It is very important to eat food from animals that have been fed their natural diet in a natural manner and season for their entire lives. Otherwise, you will be ingesting the stress that the animal endured during it's period of sub-optimal feeding.

If you want to make your own soap, find a recipe and directions online for soapmaking. Basically, you take some lye (dangerous, use caution), mix it with solid or liquid fats. The proportions and exact directions would be on the recipe you find online. I did this for an 11th-grade science project. You get ivory soap, so to speak.

Unless you really want to do the chemistry project, why not use a soap with no additives? Dr. Bronners (saponified fats) and Charlie's Soap (surfactant only) are examples that you can look up and see if you like their ingredients.

You can't use a sudsing soap in a washing machine or dishwasher. If you do, you'll get suds all over the house.

Don't expect your laundry to end up all fluffy. In a hard water area, your towels will end up kinda cardboard-y. Your family won't like it, I reckon.

The no-soap alternatives are (1) take clothes to the river and beat them on the rocks, (2) vinegar is a good cleaner, but I've never used it on the laundry.

I always have tons of leftover animal fat. I was thinking about making my own soap, but it seems like a hassle. I use the fat for awesome tallow lamps. Adding a wick is much easier than making soap.

P.S. If you are getting soap film in your dishwasher, you are not using the correct dish washing detergent for the water hardness in your area.

I was hoping we all find a way to be 120 years old and yet look like 50 year olds.

Why?

And why (arbitrarily) 50? Our appearance changes yearly during our lives. Would you have the apple be forever green and never ripen into its delicious sweetness?

Back in the early days of warnings against cows milk (in the last half of the twentieth century), the bone health of milk drinkers was compared to the bone health of cultures that do not drink milk. In examining the diet of the non-milk drinkers, calcium was found to be supplied by vegetables and seeds. Despite the fact that a milk-drinkers diet has an abundance of calcium, bone health is better is populations who get less calcium from plant sources.

Bottom line: if you avoid the unbalanced calcium in milk, bone health is easier to maintain with less daily calcium.

Cattle or sheep or oysters are not specifically designed to feed raw paleo people. Yes? No?

Curious question. In terms of what each species is designed for: each species is designed to reproduce its own kind. Collaterally, carnivorous and omnivorous species eat the flesh of other species. That's way off the logic behind each species' milk being specifically designed for its offspring. TD is talking about mammalian milk being designed to meet the growth needs of its own species. For example, a fast growing small animal's milk would have less calcium than a fast growing large animal's milk. Human milk is designed for slow growing humans and is nowhere near approximated by bovine milk.

Watch and see how many European countries will become majority Islamic in 2 or more decades.  It is inevitable, post christian zero religion is a vaccuum with seculars not reproducing, sunk with abortion, contraception, feminism, homosexuality... key principles post christian political leaders embrace so much for their population reduction policies.

Well, then, from an indiscriminately-reproducing, anti-abortion, oppress-the-women, homophobic point of view, Islam should be a breeze of fresh air.

...in 2003 i named my own 2nd boy "Moses Ishmael"... a Christian Name and a Muslim Name.  His nickname is Mish.  I figured if the Muslims win out in the future, he should go by the name Ishmael.  We must be like the bamboo and bend where the wind blows.

Moses is an Egyptian or Hebrew name. According to tradition, he was named Moses by the Egyptian Pharaoh's daughter, who found him in a river, where he was placed by his mother to spare his life when it was decreed by the Pharaoh that all Hebrew first-born sons should be killed. He was a lead figure in the scriptural history of the Hebrew people in antiquity, estimated to be a few millenia before the lifetime of the lead figure of the Christian religion.

Actually, one Hebrew name and one Islamic name is better, but Abraham would have been a better match with Ishmael because they were half brothers, each one of whom was decreed by God to be a future father of a great nation. Moses' era was much later than Abraham and Ishmael, according to scriptures that contain their histories.

I'll remain 100% skeptical until I see some parallel process for fruits and vegetables in a modern hunter-gatherer population. All I see in these paleo carry-overs are meats and fish stored in paleo-ish containment.

How are you defining paleo? What sort of evidence are you using to place your theory into the paleolithic era?

Mechanical means something was used to press the olives. Presses can be stone, metal, wood. At industrial capacity, presses and their contents can get hot.

Extraction is a more general word. Chemical solvents can indeed be used to extract oils.

Both methods lead to an oil that turns rancid quickly. You can grind/press your own olive oil. My neighbors from Morocco do that in a contraption that looks like a manual coffee grinder with a spout.

Best of all, olives can be eaten whole, while still containing the oil. While you chew them, your taste buds inform your stomach that it is about to digest an olive.

You can see pictures online of all of this if you google olive oil press. Also, search this forum for the many good threads about olives.

More feedback: Part 7 (innards) - Watch your light source (sun direction) so that you aren't showing us something that is in YOUR shadow, as happened with the liver.

Part 8 (hack saw) - add narration or annotations to say what you are cutting (flank, loin). Now I'm nitpicking - anyone who is actually going to cut up a lamb isn't going to be that ignorant, but I had to say it anyway. Once I get started, there's no stopping me.
