Still thinking about one...

Well, tired of thinking on a subject, I decided to post without one...
Where are some suggestions for those that, like me, can't find a decent subject to post about:

• The Moon's phases' effects in the paremecia's reproductive cycle on Mars. (An interesting suggestion from my brother.... I doubt that you can find paramecias in Mars....)
• The usage of plankton to produce chalk. (after working on this subject, explain it to me!)
  
• Titanium dioxide as ingredient of candies, wall inks and toothpaste and it's effects on the environment. (It's true... People eat candies with ingredients used in civil construction and in toothpaste... Titanium dioxide it's also terrible for the environment because the production of this compound is really harmful to the environment.)
• Che Guevara Agricultural Policy in North Africa (Che Guevara in North Africa???)
• Why aren't elephants pink colored?

And much more subjects that you can surely find if you use your imagination in subjects which you're acquainted to, subjects with which you deal in you daily life and others that you feel inspired to write about. Don't try to write about a subject that you're not familiar to without thinking and learning something about it, otherwise you'll find difficulties during your writing.
