The complexity, and importance, of our sense of touch is huge. Just think about reaching out for a piece of fruit on the table — you need touch to know when your fingers have reached, you need to adjust your grip so you don't squeeze it too hard, or squeeze too softly and drop it. Touch can tell you if the fruit is ripe or past its best, whether its fridge-cold or it's been sitting on the counter. As well as all that, you need touch for good movement, and for fine movement like doing up a button, and the continuous feedback from the muscles in our feet is vital to keep us from stumbling.
