I came to America, and I made good. It's an old story, but it hasn't been told in a long time. Usually, it's, 'I'm an immigrant, I came here and got persecuted.' My story is I came here, I worked hard, and it worked out all right. So it's still available.
It's a question of spreading the available energy, aerobic and anaerobic, evenly over four minutes. If you run one part too fast, you pay a price. If you run another part more slowly your overall time is slower.
