During colonial days there were no bathtubs or showers in the houses.  They were not missed, however.  Many people of that time never thought of taking a bath.  Most people thought that water caused many diseases.  Only the hands and face were washed, and that wasn't often.  You can infer that people of today:

• take more baths than people of colonial days
• take fewer baths than people of colonial days
• fear water more than people of colonial days

• darkness
• color
• distance

• attached to rocks
• in big patches
