  • You can donate blood in 20 minutes. It takes an hour plus to donate plasma

    Am I going to sit in a chair for an hour plus without any compensation? Maybe once or twice here and there. But you can donate plasma at least twice a week.

    It requires two donations for a single unit. If you donate once and don’t donate the second, then your first donation is unusable. You have to get them to donate twice.

    When I was donating plasma, it paid about $75 for each donation. 50 first, 100 for second. The money is pretty good. $300 a month is a lot for a lot of people.

    If you didn’t compensate people for plasma donations, a lot wouldn’t do it. They currently need more people to donate.

    Plasma “donation” is a good thing.

    Good take

    I wouldn’t even be against sharing some information so they could give me better ads

    I’m not in the market for a new car. I don’t need car ads.

    But knowing I shop at Something Hardware a lot and they are having a spring black friday sale on the tool I’ve been eyeing would be nice.

    Even still Something Hardware just slapping their logo in an ad is not helpful at all.

    If ads were helpful they wouldn’t be annoying

    Easy way to do %

    Say you want 6% of 45

    Seems hard right?

    1% of 45 is .45

    .45 × 6 =

    .4 × 6 = 2.4

    .05 × 6 = .3

    2.4 + .3 = 2.7

    So 6% of 45 is 2.7

    Extra:

    Say you want an item that is 40 dollars and it is 20% off.

    10% is 4 dollars.

    20% is 8 dollars.

    So item would be 32 dollars.





  • Celcius isn’t rocket science

    For 99% of things it’s simply reading a thermometer or typing in numbers on a device to set a temperature.

    Just like I would have to look up what temperature to bake my cookies, 325°F, 350°F, 400°F. I’d have to look it up to cook them in C.

    Me “knowing” the system doesn’t help me. Because I have no idea what 325°F really is. That would cook my skin, no way I’m “feeling” it. All it is is just a number to me. If I had to push 325 or 163 on my oven it makes no difference to me.

    When someone says I put a liter of gas in my car, I can reasonably think and know what a liter is. To me, the easiest way is that it’s half of a 2L of soda because soda is sold in metric liters, and it gives me a reference. I also know that a liter is basically 1/4 gallon.

    But when you say 28°C, I have nothing to compare it to. I know 40°C is really hot, and 20°C is basically room temperature. Even that doesn’t even help me. So I guess I can deduce it’s somewhere in the middle? It’s 82°F. But I have no reference to how 28°C feels.

    82°F. Is low 80’s, I know what low 80’s feels like. Easy for me to figure out the realitive temperature.

    Fahrenheit and weather temperatures just line up so good at 0-100.

    But if you just thought of 82°F as 82% hot you could easily get a general idea of how hot it is.

    Livable temperatures are between 50°F and 100°F. Humans like it halfway between the two. ~75% hot. 65°F is a cold house, 85°F is a hot house. 99% of homes are between those two and still averages to 75°F.

    1°F is smaller than 1°C.

    82°F vs 83°F a normal person wouldn’t be able to tell the difference. But you know, as it approaches 85°F or 90°F it’s definitely heating up.

    I could say 93°F. 93% hot. That’s pretty hot. I’m sure you could wrap your mind around that.

    But tell me 34°C and how am I suppose to really quickly wrap my head around that?

    6° less than the hottest realistic temperature outside? I don’t even know how 1°C drop feels, much less 6°.


    • or - 5°C

    23°F to 41°F is -5°C to 5°C

    If it’s below 40°F I’d be cautious of Ice. Once again, it doesn’t matter that water freezes at exactly 32°F at standard pressure.

    It’s like boiling water. No one puts a thermometer in water to make sure that it hits 100°C exactly.

    150°F water will scald you in a second (65°C)

    140°F water will scaled you in 3 seconds (60°C)

    120°F water will scaled you in 10 minutes (50°C)

    +100°F water has the potential to scaled you (~40°C)

    I’d rather know that +100°F water has a chance to burn me than remembering +40°C has a chance.

    That’s way more important knowledge than the freezing and boiling temperatures of water at standard pressure.

    Water freezes at 0°C at standard pressure, sea level.

    If you are above or below, it will be different.

    Saying “It’s not 0°C outside so there’s no ice on the road” is dumb. Because there could definitely be ice on the road.

    You should be looking out for other things while driving. Not if the one thermometer, who knows where, is saying that it’s 0°C or not.

    What’s 28° C? How can I envision in my mind what that means?

    0-40 as a scale. 28 is about 3/4 between the two. So it’s towards the hotter side but how far into it?

    It’s 82.4° F

    Low 80s. I know exactly how low 80’s feel.

    0-100 is easy to compare with %

    82.4° F is 82% hot.

    Humans like it around 75% hot between 50-100.

    So 82° is hot but not pushing 90s

    You can get a general idea of temperature very easy.
