Why is balance and coordination important?
Humans stand on two feet – which is a lot less sturdy than the four that most animals have. Balance is really important for humans because we walk upright. Coordination allows people to do just about everything. You need some level of coordination to be able to put food in your mouth – you need to open your mouth and put food in at the same time. At a more complex level, humans need to be able to make tools (or buy them, nowadays) and other fine motor skill activities.
