That quote in indigo ... oddly enough seems to be in disagreement to human growth.
If the same principle was followed:
No sky scrappers due to the multitude of deaths back in the industrial revolution.
No light bulbs or electricity; that shock would've made Newton sh*T himself.
7 astronauts die in 1 shuttle to the moon.
pursuit of better engines: faster, more fuel efficient, more powerful, more torque, higher speeds when laptimes decrease only by 1-5seconds every 3yrs or less.
Babies fall hundress of times when trying to walk. Some don't even bother walking unless its over long distances. My son RAN as soon as he could stand. He jumped like he was on a bouncy ball learning how to stand! Until he was 2 he only stood in 1 spot whenever Eating, staring at ******* on a blonde in the mall, or reaching for something to eat. He walked or ran when drinking.
My point keep trying if you like something, to get the best result. Only you can decide when enough is enough.
