4
Avoidance of Injury

• Pain
• Fear

5
Generalized Learning and Understanding

• Communication
• Memory
• Reasoning

6
Repair of Injury

• Clotting
• Inflammation
• Pain
• Infection fighters
• Fibrin to shrink wound

7
Burns and Frostbite

• Cells ready to replace epidermis
• Deep burns kill cells that replace epidermis
• Time and risk of infection
• Frostbite just as bad as burns
• Different reactions to dry ice vs. hot coals

8
Radiation

• Dark-skinned races prepared for sun
• Gradual exposure better
• Fish hatcheries
• Incandescent vs. Fluorescent light
• Lotions
• UV-B vs. UV-A
• Chemical reactions
• Cataracts and sunglasses

9
Regeneration of Body Parts

• Ability to regenerate not used enough
• Maintaining machinery
• Unable to control harmful growths
• Increased cell replication increases risk of
  cancer

Summary

• Pain and fear help us to avoid injury.
• Our communication, memory, and reasoning helps to
  prevent injury.
• Chemical processes and pain help to heal an
  injury.
• Burns and frostbite help us to stay away from
  sources that could contribute to injury.
• Gradual exposure to the sun is best, and sun tan
  lotion may not always be the solution to great
  exposure to the sun.
• Needed machinery to regenerate body parts is
  unavailable.
