If you don't like my opinions, leave. But just remember, animals can't leave the cages that hold them. As you cozy into your bed tonight, try to imagine the pain and the suffering that they endure day after day and night after night. Next time you get some soap in your eyes, try to imagine that pain for 3 or 4 days at a time. Next time you have a stomach ache, try to imagine liquid plumber being poured down your throat till you puke so much blood that you bleed to death. Next time you bump your head, try to imagine being a monkey and getting a steel plate smashed into your skull at 50 miles per hour. For all these things have happened in the name of science. They continue in abundance till this day.
A metrical foot of two syllables, one long (or stressed) and one short (or unstressed-the opposite of an iamb). Samuel Taylor Coleridge demonstrates the use of various kinds of metrical feet: "Trochee/ trips from/ long to/ short."
