If humans had hollow bones like birds, how much would they weigh? LIFE OR DEATH NEED AN ANSWER?

Question

since birds can fly, and they are light, if we had the same structure how much would we weigh? im really curious.

Answer 1

the skeleton of a fully grown human only weighs about 10% of their mass.. 18 or so pounds.. hollowing it out would do nothing for aviation..

birds' hollow bones help.. but so does their muscle to mass rati.. which is much higher than in most mammals
