The Wall Street Journal has an interesting article describing how appliance manufacturers are now doing a better job of designing products for aging baby boomers. One strategy they employ is to make their younger engineers wear "aging suits" to help them empathize with and better understand how more elderly users might actually experience a product. To this end, the younger workers tape up their fingers to simulate arthritis; stick cotton balls in their ears to lessen their hearing; and wear thick glasses to affect impaired vision. All-in-all the strategy seems to have delivered some impressive results and it speaks to the benefits of unlearning one's age.
