  • The goal is to take the car as little as possible. It sounds like visiting the beach and visiting your friend isn’t possible without a car, and that’s not something that you need to worry about. If there are car sharing services available in your city, like zipcar. You can still do that without committing to the $10k/year cost of owning a private car.

    Let’s say you use a car 3 times a week, twice to visit friends, and once to go to the beach. Zipcar offers a $11/hour rate, and we’ll assume you spend 4 hours on each trip. That comes out to $132/week, or $6870/year, saving you over $3k/year over owning a car. You’d no longer have to worry about maintenance or car insurance. This would also be much better for the environment, since you can use a shared car instead of dedicating a car to yourself. Any week where you don’t go to the beach, or your friend visits you, would be pure savings for you, too.

    This video is a really good video about why car-sharing is so useful:

  • They do. The eye doesn’t have “frames per second”, per se, because every neuron acts independently, instead of as a eye-wide “frame”. But the rod cells that your eye switches to for night vision have slower activation time than the cone cells, allowing them more time to capture photons, before telling the brain about what it saw. Just like how your camera switches to longer shutter times for night vision to capture more photons, before sending them to the SD card.

    Rod cells also respond more slowly to light than cones and the stimuli they receive are added over roughly 100 milliseconds. While this makes rods more sensitive to smaller amounts of light, it also means that their ability to sense temporal changes, such as quickly changing images, is less accurate than that of cones.
