Heartbreaker

Rule number one, is that you gotta have fun, But baby when you're done, you gotta be the first to run Rule number two, just don't get attached to, Somebody you could lose So le-let me tell you

This is how to be a heartbreaker Boys they like a little danger We'll get him falling for a stranger, a player Singing I lo-lo-love you

How to be a heartbreaker

Boys they like the look of danger

We'll get him falling for a stranger, a player

Singing I lo-lo-love you

At least I think I do! Cause I lo-lo-lo-love you.

In lab experiments, people have been given a variety of cognitive tasks — computerized puzzles and games, portions of I.Q. tests — and researchers have consistently found that, under normal conditions, those with slow-acting enzymes have a cognitive advantage. They have superior executive function and all it entails: they can reason, solve problems, orchestrate complex thought and better foresee consequences. They can concentrate better. This advantage appears to increase with the number of years of education. The brains of the people with the other variant, meanwhile, are comparatively lackadaisical. The fast-acting enzymes remove too much dopamine, so the overall level is too low. The prefrontal cortex simply doesn’t work as well. On that score alone, having slow-acting enzymes sounds better. There seems to be a trade-off, however, to these slow enzymes, one triggered by stress. In the absence of stress, there is a cognitive advantage. But when under stress, the advantage goes away and in fact reverses itself. “Stress floods the prefrontal cortex with dopamine,” says Adele Diamond, professor of developmental cognitive neuroscience at the University of British Columbia. A little booster hit of dopamine is normally a good thing, but the big surge brought on by stress is too much for people with the slow-acting enzyme, which can’t remove the dopamine fast enough. “Much like flooding a car engine with too much gasoline, prefrontal-cortex function melts down,” Diamond says. Other research has found that those with the slow-acting enzymes have higher I.Q.’ s, on average. One study of Beijing schoolchildren calculated the advantage to be 10 I.Q. points. But it was unclear if the cognitive advantages they had would stay with them when they were under stress outside the security of the lab environment. The Taiwan study was the first to look at the COMT gene in a high-stakes, real-life setting. Would the I.Q. advantage hold up, or would the stress undermine performance? It was the latter. The Taiwanese students with the slow-acting enzymes sank on the national exam. On average, they scored 8 percent lower than those with the fast-acting enzymes. It was as if some of the A students and B students traded places at test time. “I am not against pressure. Actually, pressure is good [for] someone,” Chang commented. “But those who are more vulnerable to stress will be more disadvantaged.”
