Estimate the weight of a typical human adult in pounds?

Asking about the average of anything is pretty useless information. 21 year olds are adults but as a group they weigh less than 50 year olds that are also adults.Females as a group weigh less than males, Asians weigh less than north americans. Mark Twain supposedly quipped " If you have one foot on fire & one on ice, Then on average you might be pretty comfortable" No one knows the exact answer to your question and it would be useless & meaningless if they did. ask a better question & you will get better answers.

How much do you have to weigh when you are 12?

Weight can vary greatly among 12-year-olds depending on factors like height, gender, and body composition. A healthy weight range can typically be determined by consulting growth charts and BMI calculations with a healthcare provider. It's important to focus on overall health and well-being rather than a specific number on the scale.
