\Life, 140 factors:
27. Ground state energy level for helium-4
28. Carbon-12 to oxygen-16 nuclear energy level ratio
29. Decay rate for beryllium-8
30. Ratio of neutron mass to proton mass
31. Initial excess of nucleons over antinucleons

Intelligent life: 402 factors:
146) level of spiral substructure in spiral galaxy
a) if too low: galaxy will not be old enough to sustain advanced life
b) if too high: gravitational chaos will disturb planetary system’s orbit about center of galaxy and thereby expose the planetary system to deadly radiation and/or disturbances by gas or dust clouds
147) mass of outer gas giant planet relative to inner gas giant planet
a) if greater than 50 percent: resonances will generate non-coplanar planetary orbits which will destabilize orbit of life-support planet
b) if less than 25 percent: mass of the inner gas giant planet necessary to adequately protect life-support planet from asteroidal and cometary collisions would be large enough to gravitationally disturb the orbit of the life-support planet
148) triggering of El Nino events by explosive volcanic eruptions
a) if too seldom: uneven rainfall distribution over continental land masses
b) if too frequent: uneven rainfall distribution over continental land masses; too much destruction by the volcanic events; drop in mean global surface temperature
