So, if you live in circumstances that do not always permit you to use your dominant hand…

You are likely to develop some competence with your non-dominant hand as well

This is why left-handed people (cuz of everything in this society being made for right-handers) are more likely to have more use of both hands.

but, please do not expect miraculous levels of ambidexterity from all left-handed people.

…not everyone can be a success story like “left-handed Bruce-Boxleitner-Tron to dual-wielding Rinzler”
