We ought to be very grateful that we have tools. Millions of years ago
people did not have them, and home projects were extremely difficult.
For example, when a primitive person wanted to put up paneling, he had
to drive the little paneling nails into the cave wall with his bare
fist, so generally the paneling wound up getting spattered with
primitive blood, which isn't really all that bad when you consider how
ugly paneling is to begin with.
