  • If the 300m people lived in the same area and you got a true random sample.

    Sunsets at 9:09 today in Michigan

    Sunsets at 8:04 today in California

    Sunsets at 8:34 today in North Carolina

    Sunsets at 7:57 today in Alabama

    Sunsets at 7:38 today in Arizona (They are on standard time)

    Sunsets at 7:13 today in Hawaii

    Sunsets at 11:36 today in Alaska

    Someone in Arizona might want the sun to set at 7:38. It’s blazing hot all day.

    Someone in Michigan might be fine with sunsetting at 8:08 with standard time.

    Someone in Alabama might not want the sun to set at 6:57.

    Someone in Hawaii probably doesn’t want the sun to set at 6:13.

    Even if you split up the 1000 people to equally represent all states, that’s only 20 people per state.











  • There are the “I like to keep my house at 66°F because I like to wear a hoodie or use a blanket”. They are going to say that 75°F is warm or even hot for a room.

    If an average person sat naked in a 75°F room they would be happy.

    68°F or 20°C is cold for me. Even 70°F or 21°C. I keep my house around 72° to 74°F and bump it up or down a degree. Coming in from mowing the yard, bump it down, sitting all day watching movies, keep it the same, cold winter day, bump it up.

    Older people keep their houses at 78°+

    100°F doesn’t mean “not fit for human habitation”

    Anything above body temperature of 98.6°F (37°C) you are slowly cooking yourself. That’s why 100°F is important.


  • Yeah, they can weigh up to 2000lbs with a king-size bed. A king-size bed is 6,080 sq in.

    A fridge can weigh 300lb being 36"×30". 1,152 sq in.

    Fridge is .26 pounds per sq inch. A water bed is .33 pounds per sq inch.

    So while heavy the weight is distributed basically like a fridge. This is assuming an empty fridge.

    As for durability, a quality waterbed mattress is thick. You aren’t going to pop it or cut it without deliberately trying to.

    Even if you took a knife and stabbed it from the top, it’s not going to leak until you put weight on it.


  • 50°F is the point where you need clothes to survive. If you sat naked in a 50°F room you run the risk of your body not being able to generate enough heat and you’ll slowly die.

    ~75°F is room temperature. It’s in the middle on the warm side.

    70°F is a cool room, 80°F is a warm room.

    Whenever I think of Celsius I see it as 0° to 40° with 20° being room temperature. I hear 30°C and think halfway between 70 and 100 so I know it’s around 85°F and I know how 85°F feels.

    But like 35°C. That’s 3/4 of the way from 20°C to 40°F. 100°F-70°F is 30°. 3/4 of 30 is 22.5. So 35° must be close to 70°+22.5° or ~93°F. I know how 93°F feels.

    I can see how celcius is easier if you learned it as a child. 35°C would just be 35°C. But trying to quickly wrap your head around it is difficult unless you just know it. I’m sure if I said 93°F you could tell me that that is pretty hot.


  • You never deal with 0°C/32°F or 100°C/212°F unless you’re in a science lab.

    They are nice numbers in celcius, but for real-world applications, it’s almost meaningless.

    When I boil water on the stove, I don’t check if it hits 100°C. When I freeze water in the freezer, I don’t check if it hits 0°C.

    Everyone can get by without knowing the exact degrees.

    This is pure water at standard pressure. Higher or lower altitudes will change it, and if your water has minerals or impurities in it, it will also change it. It’s pretty arbitrary.

    Water on roads can freeze before it hits 0°C outside. It can even snow above 0°C.

    Fahrenheit is a very simple scale other than those two things. <0° extremely cold, >100° extremely hot for air temperature. Freezers are 0°F and Saunas are 200°F. Hot tubs are 100°F. You bake cookies at 325° to 375°, pizza is cooked at 600° to 800°F. You’ll find a lot of 25° increments in cooking.

    Fahrenheit isn’t really a part of the US customary units.

    Knowing both Fahrenheit and Celsius, I do think Fahrenheit is simpler for real-world applications. For science they are just numbers on a scale. Converting is the only real problem.


  • 1 centiyard is about equal to 1 centimeter

    1 miliyard is 3 milifeet

    1 kiloyard is 3 kilofeet

    It would be the same as the metic system having something like a “hand”

    That if you wanted to express 1/3 of a meter you could just call it 1 hand. 2/3 meter would be 2 hands.

    If you were using this metric system and knew that something had to be two hands long. You’d simply call it 2 hands instead of .66 meters or 66 centimeters.

    If something had to be 2.5 hands long it would be .825 meters or 82.5 centimeters

    Meter and yard are both random established lengths. Using miliyards or millimeters is exactly the same.

    US customary units just have smaller unit names you can call them if it is convenient. If you never wanted to use anything but yards like the metric system does meters, it’s possible. Don’t want to use miles? Then megayards.

    I do think 1 simple system that everyone uses is needed and the metric system is simple.

    But if stupid Americans can use the “difficult” system, it can’t be too hard.


  • That’s a misconception for water beds.

    High-quality water beds have stabilizer pads in the mattress

    The idea of the old crappy 70’s water bed where they slosh around is a poor idea.

    You aren’t laying on a ziploc bag barely filled with any water.

    It’s more like a ziploc bag filled with molasses. If I pushed a corner down it would slowly bring up everywhere else. If I stopped pushing a corner it everything would slowly go back down.

    Say I have a massive gut and sleeping on my right side. I’m displacing X amount of water. If I was to turn to my left side I am still displacing the same amount of water. Just the empty space that use to hold my gut would be filled with the water from the other side where my gut is now. Someone on other side of bed wouldn’t even feel it because the water underneath them doesn’t change.


  • This is why water beds are amazing

    Winter you put memory foam to keep you from the cold water, in summer you sleep on the cold water.

    Only downsides to a water bed are: 1. Heavy 2. You have to add chemicals to your mattress as regular maintenance 3. It can’t really be extra firm (but a lot more firm than people think)

    The water will steal every bit of heat from your body, but you’ll stay warm with a blanket
