In fact, researchers have found a multitude of studies showing that shorter people generally live longer than taller people, and this isn't just some random coincidence that scientists are confusing with a real pattern -- they base these findings on studies that have been done all over the world. For example, the longest-living people are from Okinawa, Japan, and the average height of their elderly is a mere 4'9". They've also found that taller people contract heart disease and cancer more easily, while in shorter cultures, such as some African tribes, these diseases are virtually nonexistent.
"Hold on, smart guy," you may be thinking, "If this is true, then why do scientists say that we're getting taller on average, as well as living longer?" Well, it probably has a lot to do with the fact that our knowledge of medicine is much better than it used to be. While taller people are generally more sickly, we have the medical expertise to kind of keep up with it.
"Damn, our deductible's going to go up again, isn't it?"
How are we so sure? Because coronary heart disease was rarer than a healthy meal at Taco Bell back before the 20th century, during a time when people were on average 4 inches shorter than today. And in countries whose populations have only recently increased in height, such as Singapore and India? Yep -- CHD is more prevalent.
