My chosen equipment is a stool I am currently making in my Furniture Construction class. Before I made the furniture, I tried to incorporate certain ergonomic principles or anthropometric variables in the measurements of the height and width of the stool - only that it was not up to the ISO standards, but to my body's standards. :)
I took into consideration the following anthropometric variables:
1) Lower leg length - vertical distance from the floor to the lowest part of the thigh behind the knee (90 degrees of knee flexion)
2) Hip breadth - maximum horizontal distance across the hips, while sitting down
3) Body depth - horizontal distance from the rear of the knee to the back of the buttock, while sitting down
I measured the height of the stool to about 18 inches plus a cushion of about an inch. The stool is round so the diameter works for both the hip breadth and body depth, which is measured at 17 inches. These measurements are basically based on my body size, allowing me enough space to sit on the cushion and allowing my feet to touch the ground at a comfortable level.

Cradle to Cradle.

This green book is all about "remaking the way we make things." It gives us a different perspective of recycling as opposed to upcycling - if a product does actually become more useful or harmful when it is recycled, or if upcylcing or developing a better product than that which it came from is more effective.
When we create and develop products we must be concerned of its evolution. What happens to a product once the user decides to dispose of it - does it just rot in our environment or does it help sustain our environment? This is where the question of Cradle to Grave or Cradle to Cradle becomes significant. Why not make things that once the user is done utilizing it, they can be thrown on the ground and thus sustain every living organism around it - just like nature. The book compares this relationship to a cherry blossom tree, whose "litter" sustains the soil around it, or a colony of ants - how their way of living is so sustainable that what they take from nature they give back to support the ecosystem. I mean you don't see them having a dumpsite beside every anthill right? Lol. I now have high respect for these creatures. This is apparently how nature works, and unfortunately not how man does.
The book further talks about sustainable design (like a grass roof - and no, not our nipa huts that use dried grass) and how being "less bad' just won't cut it. Here are several quotes to ponder on from the book of William McDonough and Michael Braungart:

Get "free of" known culprits. The detergent may be "free of" phosphates, but have they been replaced by something worse?
Follow informed personal preferences: prefer ecological intelligence, prefer respect, prefer delight, celebration, and fun.
Create a "passive positive" list. What, if any, are their problematic or potentially problematic characteristics? Are they toxic? Carcinogenic? How is the product used, and what is its end state? What are the effects and possible effects on the local and global communities?
Activate the positive list. Stop trying to be less bad and start figuring out how to be good. Now you set out with eco-effective principles, so that the product is designed from beginning to end to become food for either biological or technical metabolisms. (No more substituting harmful ingredients to less harmful ones).
Reinvent. Recast the design assignment: not "design a car" but "design a "nutrivehicle." Don't just reinvent the recipe, rethink the menu.
How can we support and perpetuate the rights of all living things to share in a world of abundance? How can we love the children of all species - not just our own - for all time? Imagine what a world of prosperity and health in the future will look like, and begin designing for it right now. What would it mean to become, once again, native to this place, the Earth - the home of all our relations? This is going to take us all, and it is going to take forever. But then, that's the point.

Bikram Yoga.
Bikram Yoga is yoga in a heated room. This allows muscles and tissues to become more elastic giving you more flexibility and less chance of injury. It also allows you to sweat and detox through the skin. It also improves your circulatory and cardiovascular system plus it provides other health and stamina benefits. For me though I think the most important benefit one can get from it is that it releases great stress from the mind and the body.
Below are 3 Bikram Yoga poses:

1) Dandayamana-Bibhaktapada-Janushirasana COG: the perpendicular line where the torso, head and left knee are located Size and shape of the base: long line from the hands back to the right foot Postural stress: in this position, the stomach is sucked in to create compression of the abdominal organs and to stabilize the spine
2) Dhanurasana COG: the upper torso of the body that pulls on the legs for support Size and shape of the base: square/rectangular shape where the abdomen touches the floor Postural stress: this position opens up the rib cage, stretches the abdominal wall, and gives the spine a 360-degree flexion
3) Tuladandasana COG: on the left leg standing Size and shape of the base: the left foot along with the stretched body that forms a capital "T" Postural stress: to maintain this position, the muscles of the horizontal body must be pulled on separate ends simultaneously as if in a human tug-of-war

Anatomy, posture and body mechanics.
Activity 1: Stand with your back and heels against a wall. Now try to bend over as if you were picking something up off the ground just in front of you. What happens and why?
Answer: The further I go down, the more I tend to move forward and lose my balance. As soon as I feel I'm about to fall forward, I put my right foot in front of the other to catch myself from falling. The COG of the body must fall within the base of support (such as the feet) and postural reflexes must exist (like moving a foot forward) so that the total body mass remains balanced. If a person standing leans forward to pick up something from the ground, the pelvis moves rearward to compensate for the forward displacement of the COG of the upper body. But in this example, the wall is preventing the pelvis from making its rearward move. Hence, the body will fall over, unless a foot is placed forward - this will balance the transfer of the COG. Sufficient space around a standing body and room for the feet are therefore needed to avoid loss of balance.
Activity 2: Find a chair and place it with its back against a wall. Lean over the chair and touch your head to the wall - make your back as parallel to the ground as possible. Can you lift the chair and stand up?
Answer: Yes I did, on the first try. It was a medium to heavy-weight chair. Women can do this better than men probably because the COG of a woman's body is lower than that of a man's body. I've read that women have a bigger pelvis area (which allows women to carry a baby when pregnant) thus making her body mass concentrated on the lower portion of her body - as well as her COG. Men on the other hand, have their COG concentrated higher towards the chest area. This therefore makes it harder for them to carry something when their chest is already bent forward.
Activity 3: *I haven't done this because I don't live at my house and therefore don't think I can write on the walls... :)
Answer: The intervertebral discs in our spine have a "viscoelastic" behavior. This means that they deform initially then return rapidly to its original shape when a force is removed - elasticity. They may also become narrow as fluid is expelled and the superior and inferior vertebral bodies move closer together (when compressed), and fluid moves into the disc as the disc space becomes wider (when stretched) - viscosity. These occur as a result of the forces exerted on the spine due to daily normal activities. The shrinkage and expansion of the disc spaces change the measure of a body's stature. This is why some people are taller when they wake up in the morning than when they go to bed at night. According to the book, people are about 1% taller when they wake up and almost 50% of the stature gained is lost in the first half-hour after rising.
