100kg isn't a particularly large mass for an adult. Particularly not these days.

I mass ~100kg, and at 182cm tall, am not unhealthily overweight. If I get down to 90kg, I look and feel underweight.

BMI calculator says you're obese.

Allowing husbands to be present in the room when their wives give birth has a greater gravitational effect on a newborn than the Sun, Moon, or planets. I wonder if astrologers have taken this late twentieth century change in social norms into account in preparing their charts. ;)

I think even more relevant is changes in birthing approaches. More friendly rooms (thus not full of hospital equipment) and especially water birth. If she's not in the center of the birthing pool that will have an even bigger effect.

BMI may be a useful metric for populations but not individuals.

BMI is absurd.

Dimensional analysis alone demonstrates this; WTF about my health can be measured in kg.m-2, and why?

The entire measure is designed to make people worry that they are obese.

Does this person look obese to you? (I was almost 110kg when this was taken, and was certainly overweight, but obese?)

 Human body weight - I was using a rough approximation when I used 100 kg. Average adult human body masses, by country and sex:
  • United States: m 90.6 kg (199.7 lb) - f 77.5 kg (170.9 lb)
  • Canada: m 84.6 kg (187 lb) - f 70.1 kg (155 lb)
  • France: m 77.1 kg (170 lb) - f 62.7 kg (138 lb)
  • South Korea: m 73.34 kg (161.7 lb) - f 58.29 kg (128.5 lb)
  • Russia: m 70.6 kg (155.6 lb) - f 60.2 kg (132.7 lb)
  • India: m 65.0 kg (143.3 lb) - f 55.0 kg (121.3 lb)

Fit & trim, by 'Murkin standards.
Problem for you:
You have a cylindrical form...
What would be the diameter of a 6' tall, 150lb pillar of coolwhip?
Bonus: how much more dense would the bottom foot of it be than the top foot? (How much more Coolwhip will this require than a 1' tall cylinder?)
And 6' of plutonium?
Thanks - these are things I hope to need some day, and don't know anyone else who I trust to tackle the problem. :)
 
Plutonium has a density of about 20 tonnes per cubic metre, and 150lb is 68kg, so 150lb of Pu is 68/20000 = 0.0034m3 in volume.

0.0034m3 is 3,400cm3, and 6' is 183cm, so a 6' cylinder of Pu massing 150lb has a cross sectional area of 3,400cm3/183cm = 18.58cm2.

Area is pi x the square of the radius, so the radius of your cylinder is the squareroot of 18.58cm2/3.14, which is the square root of 5.92cm2, which is 2.43cm, or just less than 1" (0.96").

As to your other problem, I have a problem with your problem, in that my knowledge of plutonium far outweighs my knowledge of coolwhip.

Though I did google the density of Plutonium, so when ASIO arrest me, I shall be depending on you as my alibi. I fear that ignorance of coolwhip is no defence in law.

Cool Whip is mostly air and has a density of 0.22–0.27 grams/cubic centimeter. It has 25 calories per serving, which is the ridiculous amount of 2 tablespoons. No one in history has limited one serving to 2 table spoons. This compares to 104 calories for the equivalent volume of whipped cream, but in defense of whipped cream, more calories are burned whipping the cream, than by prying the lid off a tub of cool whip.

The radioactive half life is about 7600 years, but the shelf life of a sealed and refrigerated tub is 2 weeks.

I think you can actually have your cylinder without it blowing up on you.

But the plain sphere critical mass is a pretty small ball. Thicker than your cylinder. And your cylinder has no meaningful neutron escape from the ends. And the more I think about it the closer to critical I think your cylinder is. The surface of a sphere goes at 4pi*r^2. The surface area of a cylinder goes at pi*r^2*h--but since we are looking at a section of a cylinder the neutrons "lost" are equal to the neutrons it will receive from that part and thus h drops out of the equation. Thus we are left with the sphere having 4x the surface area (and thus neutron loss) as the cylinder slice. Now you're making me pollute my search history even more as I didn't do the math yesterday with enough precision.... A 10kg (bare sphere critical mass for plutonium) has a radius of 4.94cm. 4.94cm/2.43cm = 2.032. If I haven't messed the modelling up the sphere has 4.13 the neutron creation and 4x the neutron loss giving a multiplication factor of .96 for the cylinder slice. 4% from critical, which I think is meaningless as I would be surprised if that 10kg figure was accurate to two digits.

The surface area of a cylinder would be (2*pi*r*h) + (2*pi*r^2). Excluding the end surfaces, it's just 2*pi*r*h, where h is the length of the cylinder section under consideration.

Pedantry. Anyhow it appears that its BMI is on a downward trajectory, however slowly, as its weight loss will only fractionally occur at the ends.

I need to eat more. 5’11” and under 150lbs? I’m like a plutonium stick! Never been over 165, but prefer to be around 155-160. Too much activity?
