Normal human sperm cells as seen through a microscope, enlarged by a few million times. Notice the huge heads and long tails. The latter are used for swimming through a thick viscous medium all the way to the egg. The journey has been likened to swimming across the Pacific Ocean in a thick sugary water!

Eric, my friend, if you are reading this, let me remind you that you are over 30 years of age. Go find a girlfriend or a wife. You desperately need to get laid soon, man!
