Look at your fingers. Which is longer? Is it the index finger (the finger you use to point with— technically the second digit, or 2D, counting the thumb), or the ring finger (the fourth digit, or 4D)?

The relative length of the index and ring fingers is known as the digit ratio or the 2D:4D. For example, if your index finger is 2.9 inches (or 7.4 cm) long, and your ring finger is 3.1 inches (or 7.9 cm) long, your digit ratio is 0.935 (i.e., 2.9/3.1 or 7.4/7.9). Men typically have lower digit ratios (the ring finger in males is typically longer than the index finger) than females (the fingers are about the same length in females). The ratio does not change much with age.

It’s all part of the company’s continuing long game for social relevance. Despite the fact that it lost 1 million users, the company also posted $100 million in profit during last week’s earnings.

In Part 1 of this series called “Why U.S. Household Wealth Is In A Bubble,” I explained why America’s post-Great Recession wealth boom is driven by a tremendous bubble that will end in tears.

In Part 2 of this series, I will go into more detail about the U.S. stock market bubble that is a major driver of the overall household wealth bubble. Common stocks – including those held indirectly in mutual funds – are one of the largest components of U.S. household wealth, along with bonds and housing. When stocks are extremely inflated, like they were during the late-1990s Dot-com bubble, they contribute to the inflation of household wealth. Conversely, when stocks experience a bear market, like they did when the Dot-com bubble popped, household wealth falls as well. In this piece, I will show a wide variety of charts and other data that prove beyond a reasonable doubt that the U.S. stock market is excessively inflated and heading for serious pain.

If there is one study that really puts the "long" in longitudinal, it's the Harvard Study of Adult Development. It has been providing data on the same group of men since 1938. There were 268 of them then – fewer than 20 are still alive – all Harvard sophomores, including future President John F. Kennedy and future Washington Post editor Ben Bradlee. The goal of the study was to find out what factors lead to healthy and happy lives. And perhaps the biggest key to well-being, it has revealed, is having friends.
