Final answer:
It is false that muscular and heavier individuals will generally show the effects of alcohol more slowly than thinner, lighter individuals due to differences in body composition and the individual variability in alcohol metabolism.
Step-by-step explanation:
It is false that people who are larger, heavier, and more muscular will generally show the effects of alcohol more slowly than someone who is thin, light, and small. The immediate effect of alcohol on a person depends on various factors including blood alcohol concentration (BAC), age, sex, health condition, and individual tolerance. Though it may seem counterintuitive, increased body mass, especially with higher muscle content, can typically process alcohol more efficiently due to higher water content in muscle tissues compared to fat. This means that the alcohol is diluted more and metabolized at a slightly faster rate. However, individual responses can vary widely.
