43 / 100
Mixed

The text states that frowning uses 42 facial muscles, while extending your arm to hit someone uses 4 muscles.

Infact verdict: Mixed (43/100).

The claims about the number of muscles used to frown and extend the arm are based on popular myths rather than scientific evidence. No authoritative sources confirm the exact number of muscles involved in these actions. The evidence consists mainly of social media posts and memes, which are not reliable sources for anatomical facts. Therefore, both claims are misleading and lack scientific backing.
