Blood makes up about 7% of your body's weight. The average adult has 10 pints of blood in his or her body. One unit of blood is roughly the equivalent of one pint. This proportion is much greater in children, and slightly different in men and women. Men, on average, have 8 to 10 pints, while women have 5 to 8 pints.
A software engineering career path is a great choice for anyone interested in the application of computer science, engineering and mathematical principles to the development of software systems.
When looking at software engineers I see 4 tiers of skills: Luminary, Senior, Mid-Level and Junior. Luminary (10+ years) is one who has mastered a skill and has set about improving their respective discipline. Some examples include: Ted Neward, Uncle Bob Martin, Donald Knuth, Oren Eini, Peter Norvig, Linus Torvalds.
