When cyclists form a paceline, everyone behind the lead rider gets the benefit of drafting. It makes a huge difference. A rider in the middle of the pack expends 25 percent less energy to go just as fast. Each rider takes his turn, spending a little time at the front, then falling back to the end of the line. That way, each person contributes a little bit of effort, everyone benefits, and we all go much faster than we could alone.
Although the road to eradicating cancer is a long one, we can get there in the exact same way. If everyone gives a little bit, we all benefit, and we all reach our goal faster: a world free of cancer.
