p021 [ [https://en.wikipedia.org/wiki/J._B._S._Haldane | J.B.S. Haldane ]] You can drop a mouse down a thousand-yard mine shaft and, on arriving at the bottom, it gets a slight shock and walks away. A rat would probably be killed, though it can fall safely from the eleventh story of a building, a man is broken, a horse splashes.
- p023 sprinting up stairs 7x to 14x more energy expensive than sitting reading
- p023 insect flight 100 beats per second, 50 to 150x more energy expensive than rest

p052 Manx Shearwater at least 55 years, LQ of 6, migrates annually from North Atlantic to Brazil or Argentina
- p053 Turkey breast meat (flight muscle) adapted for energy bursts, "drumsticks" dark with myoglobin for running endurance
p054 ruby-throated hummingbird 40℃ 104℉ endothermic, 80 wingbeats per second
- p055 twice fly 600 miles nonstop migrating across Caribbean, live more than 9 years
p055 broad-tailed hummingbird at least 12 years
- p056 birds make fewer free radicals than mammals, can withstand more free radical damage
- p057 Medical researchers study short-lived animals, author desires much longer studies
so we can live longer, so researchers have time for longer studies

p104 winged female nuptual flight with males, stores sperm.

- p104 Females develop from fertilized eggs and stored sperm, males from unfertilized eggs
- p105 Sisters share 3/4 of genes, 50% from mother and 25% with brothers
p105 Closer relatives with sisters than parents eusociality fosters complex societies

Sixth International Congress of the International Union for the Study of Social Insects (IUSSI)
- p108 Ant and termite queens produce 1 egg per minute for decades, high energy needs
- p109 queens and nest-bound drones long lived
- no cancer ... no need to repair damage, so no cell reproduction system to go haywire
p111 Royal Jelly

How many atoms in human body?
- Total Earth biomass 550 GT carbon 5.5 x 1e2 x 1e9 x 1e6 (tonnes per gram) = 5.5e17 grams
- carbon is 12 amu and 12% of the atoms in human body
- Avogadro's number 6e23, hence one gram of human carbon is 5e22 atoms
- Associated with (100/12)*5e22 ≈ 4e21 total atoms per gram of human carbon
Fermi estimate: Total Earth biomass 5.5e17 * 4e21 atoms = 2e39 biomass atoms if humans representative
- There are 1e22 to 1e24 stars in the universe
- Thousands of asteroids and trillions of comets and icy bodies orbit the Sun
- Perhaps 3e12 comets per star times 1e24 stars is 6e36 icy bodies in the universe, not counting unbound bodies
- that's a LOT of physics
- Both biology and physics are complicated ... or simple, if one is a simpleton
