Why does your stomach trademark boom does it really be a sign of you have need of to chomp through?
Its something like your brain sending signals to your stomach which cause one of your organs (cant remember which one) to vibrate which cause the noise. It commonly means that you entail to eat something specific to procure a vitamin etc, it does not always anticipate that you are hungry.
It always happen to me when I'm really hungry and it's gone when I eat. I infer it's nothing. Take contemplation.
