Ana Swanson asks: “Have you ever observed that time seems to be going by faster as you get older?” Well, have you? Check out this website by the Austrian designer Maximilian Kiener, which visualizes the passage of time as one ages. In words, when you are one year old, a year is 100% of your life. But the proportion falls sharply as you age. As you become older, each year takes significantly less time to pass by than the first. By the time you’re eight, for example, a year is only 12.5% of your life. By the time you reach 18 (the legal drinking age in Puerto Rico, by the way), that proportion has fallen by half again: one year is now 5.56% of your life. As Mr Kiener writes, your summer vacation in your first year of college feels as long as your whole 76th year. After you reach 30, the proportion begins to level off, and each year of your life is similarly short. By the time you’re 35, one year represents just 2.86% of your life …

Dr Marilyn Wedge writes: “In the United States, at least 9 percent of school-aged children have been diagnosed with ADHD, and are taking pharmaceutical medications. In France, the percentage of kids diagnosed and medicated for ADHD is less than 0.5 percent. How has the epidemic of ADHD—firmly established in the U.S.—almost completely passed over children in France?” You probably already know the answer to this question, but here’s a link to Dr Wedge’s post on this subject just in case.

Why won’t the United States and her allies stand up for the territorial integrity of Ukraine? (Right, Ukraine, unlike Kuwait or Iraq, doesn’t have any major oil reserves.) By the way, note the red border line. That is the part of Ukraine’s border that is not under Kiev’s control.
