Alternatively, your brain is way more 'energetic' when you are younger. You feel things more strongly, can be over whelmed with all the competing signals and are inexperienced. Maturity does reduce the sensitivity and improve the focus (e.g. pruning of the neocortex). But I also think experience helps too e.g. Knowing your body is feeling anger you are experienced enough to walk away or not send that email. 'Not giving a fuck' is also a strategy to avoid harmful repetition of negative memories.
