Background: One widely-used metric for encouraging people to maintain a healthy weight is “BMI” (Body Mass Index), which is defined as BMI = (weight / height²), when given a weight* in kilograms and height in meters. [*] Or “mass,” for the highly pedantic. The Issue: Doctors often recommend that humans maintain a BMI in the 18.5–25.0 range, although the…

Background: Many cities have restrictive zoning requirements that, perhaps justifiably, prevent certain types of construction (for example, building a pesticide manufacturing plant next to an elementary school). Some restrictions are a bit more arbitrary: many “homeowners associations” (HOAs) enforce extremely specific details about the exact shades of beige that a garage door can be painted,…
-
Background: Various states of mind, like anxiety, general stress, ennui, are relatively “high level,” and are not immediately related to fight-or-flight survival. Thus, there is a possibility of them being displaced by “higher priority” emotions: e.g. if you’re falling off the top of a skyscraper with only a pool umbrella to use to possibly survive,…
-
Background: Cars, trucks, motorcycles, and bicycles all share the roadways.However, drivers often entirely fail to notice bicyclists and motorcyclists. One study even suggests that drivers may often literally tune them out entirely: https://www.google.com/search?q=car+drivers+don%27t+notice+bicycles+study. For this particular idea, let’s focus on motorcycles, although the same general principle will also apply to bicycles. The Issue: At night,…

Background: Traditional societies in Middle Ages Europe had a somewhat different idea about the nature of illnesses and medicine, which included a theory that the body’s health was regulated by “four humours” (https://en.wikipedia.org/wiki/Humorism, also see Fig. 1), a lack of awareness of bacteria or other microorganisms, and a freeform approach to medical treatment. The Issue:…

Background: Certain types of apartment / home arrangements are rare in the United States (e.g. courtyard apartments or a second “back” unit behind a front house). Such residences are often not directly visible from the road, and accessing them may require going through a gate. They may also have addresses that include fractions or letters,…

Background: Many types of candy come in pre-wrapped miniature single-serving (or “fun sized”) pieces, especially as Halloween candy. The Issue: For many people, it can be difficult to avoid eating an entire bag / bowl / other-type-of-container of candy. Proposal: We can create a candy dispenser that works as follows: first, the user fills the…

The Issue: Climbing tall mountains is inherently unsafe. Dangers include falling, high winds, frostbite, venomous snakes, attack by eagles, and the high altitude “DEATH ZONE,” which really makes the whole peak-conquering thing seem like a bad idea. Additionally, this high degree of danger makes it impractical for children, the elderly, and the handicapped to fully…
-
Background: According to the American Dental Association, the “general” recommendation is for people to brush their teeth for two-ish minutes, twice a day. The Issue: Two minutes is a long time! Maybe there’s some way to motivate people to brush their teeth for this long. Proposal: The incentive is simple: two-minute videos that are only…
-
Background: Various governments and organizations have made efforts to reduce the number of firearm discharges by impulsive and/or unqualified individuals. The Issue: Currently, by design, a firearm is relatively easy to operate. Unfortunately, this makes it easy to accidentally fire, or for a child to find a gun and shoot it. Additionally, an individual may…
