Time for weekly blog post!

In today's post, we're going to discuss Choosing a Good Test Subject.

To choose a good test subject, they must have several traits.

• Lack of the following personality flaws
- Cowardice
- Impaired motor skills
- Poor judgement
- Fear of:
o heights
o weights
o depths
o bullets
o fire
• Lack of or extremely low tenacity
• Lack of any mental or physical disorders (unless for specialized testing)
• Lack of superpowers or mutations
• Between the age of 15 and 35 (this may vary for non-human species).

Test subjects under the prior requirements are good for a standard testing environment. These test subjects will not develop schizophrenic traits, nor will they leave the testing area or attempt to kill you. By following these requirements for a test subject, you can have a safe, successful, and scientific test.
