There doesn’t appear to be a calling in society to be ambidextrous, but the fact that there isn’t is no credit for those who don’t believe in the value of being ambidextrous. The fact of the matter is that when it comes to certain tasks, sports, music, and other activities, there is a distinct advantage for those that are not stuck with having just one dominant hand, because these people can use both hands equally well, which reduces fatigue and allows them to be more effective, coordinated, and efficient, for having properly developed the muscle memory in both hands. For example, when it comes to sports, we find that many players “throw like a girl” when they use their non-dominant hand, mainly because that hand has not been trained to throw for it has not practiced the tasks needed to develop the muscle memory to do so -- even though the person so trying to throw with their non-dominate hand, is quite familiar with the logistics of what makes for a good throw.
So, too, those who are under a lot of pressure to get certain work accomplished or other tasks done can find that when that activity requires the constant repeated usage of just one hand, their hand can become tired and fatigued over a period of time; whereas, if they were ambidextrous, they could distribute the work more equally between their hands instead.
Additionally, injuries are a way of life, and whenever our hand or fingers of our dominant hand have been injured, the quality of our life is impacted rather negatively because having failed to develop the skill set so needed to accomplish the same sorts of tasks with our non-dominant hand, we suffer for that lack of preparedness.
While it is true that most of us are not required to be ambidextrous to do what we need to do, it is amazing to find out, just how dependent we are upon our dominant hand, in which, common tasks such as opening a can, or spooning out food, or writing down notes, or operating our cellphone, become not just a lot more difficult, but seemingly impossible without our dominant hand, even when we know that our non-dominant hand has the same sort of capability, itself, to accomplish this. The issue, therefore, is the fact that our non-dominant hand has not been trained, which basically is indicative that it could be trained, if only we would devote some time and energy in doing so.
In consideration, that while we don’t need to be ambidextrous, it does seem worthwhile, to at least attempt to do some tasks, even as simple as brushing our teeth, eating, tying our shoes, or shaving with our non-denominate hand so as to develop some of those motor skills so necessary, that would not only make us to be more flexible in the way that we do common things, but would permit us to understand better that which we take for granted, because the reason that we are so good with our dominant hand is because of the practice and devotion that we have put into developing that, in the first place.
