### powerful anti-aging factors:

Antioxidant nutrient
* Most antioxidant nutrients have difficulty penetrating cell membranes.
* are powerful anti-aging factors
  - present in higher doses among vegetarian diets
  - the protectors of the human body
  - vitamin E, vitamin C, selenium and melatonin
* behave differently at various levels of intake.
* vary in their effects on oxidative stress in chondrocytes.
* work together synergistically.

### powerful oxidizer:

Sodium nitrate
* is chemical compounds
  - included in fertilizers
  - inorganic compounds
  - ionic compounds
  - nitrate
  - salt
  - toxic substances
* is used in dry cured meat, because it slowly breaks down into nitrite
  - to make gunpowder
* powerful oxidizer.
* white solid very soluble in water.

### powerful oxidizing agent:

Liquid oxygen
* can increase fire hazards by enhancing the inflammability of combustible materials.
* forms highly explosive mixtures with many organic materials.
* has a slight blue color.
* is added in an oxygen mole fraction exists in the test medium.
* is also a key propellant when used with hydrocarbon fuels
  - slightly paramagnetic
  - attracted to the magnet and can be clearly seen to flow towards it
  - cryogenic liquid
  - expensive
* is made by cooling the oxygen gas, which changes it to a liquid form
  - to flow past a strong magnet
  - obtained from air by fractional distillation
* is pale blue and odorless
  - the standard oxidizer used in the largest United States rocket engines
  - used as an oxidizer in the fuel systems of large rockets
* powerful oxidizing agent.

### powerful relaxation inducer:

Flotation therapy
* is essentially a process of placing the body into a state of total relaxation
  - sensory isolation
* powerful relaxation inducer.

### powerful spiritual force:

Human intellect
* powerful spiritual force.
* responds to attributes that it can easily relate to.

Caffeine addiction
* does exist.
* is powerful.

### practical system:

Boolean algebra
* 'practical' system.
* Every Boolean algebra is trivially a lattice.
* describes ideal combinational circuits.
* has wide applications in telephone switching and the design of modern computers.
* includes five axioms.
* is about things being true and false
  - also of prime importance to the design of modern computers
  - an axiomatic system like Euclidean geometry
  - applied to logic gates, combinational logic, and sequential logic
  - concerned with operations on general or class terms
  - exactly like normal algebra, except that variables have one of only two values
  - presented and used to understand the design of digital circuits
  - the manipulation of logical statements to determine truth or false
  - used to describe the behavior of a circuit constructed of gates
+ Truth, True & false in logic and philosophy: Logic
  * Aristotle was the first to put logic into a formal framework. Boolean algebra is about things being true and false.

### practiced behavior:

Authentic love
* is the attraction of dissimilarlties.
* practiced behavior.

### practitioners art:
