$0......... 99.9999999999999999....% of humans don't give a shit about how big your arms measure(and that's putting it mildly).
However, if you're in your own world and you convince yourself otherwise...by all means, spend your hard-earned $ on drugs that can fuck you up later on in your life.
So that means you never drink alcohol, don't smoke, don't stay out late, never eat pizza, red meat, burgers, don't drink milk, live in the woods but not deep enough for bears to be there.....
Thought so....
99.99% of humans don't give a shit about others, so that means if I want my arms to be big I don't give a shit what others think about it.
