F

                 The new illustrated alphabet Part 6: F is for FOG.

Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. Fog can be considered a type of low-lying cloud usually resembling stratus, and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog has affected many human activities, such as shipping, travel, and warfare. Fog also affects the brain, particularly once you reach a certain age. That actual age remains a closely guarded secret and I'm not prepared to say anymore about it.
