PART 1:
 Identify at least three different items in your everyday life that clearly incorporate ergonomic design. For each of these items, list the item, describe the ergonomic design, and explain the ergonomic benefit (how does the ergonomic design improve the item and reduce injury potential or increase efficiency).
PART 2:
 Identify an item that could be improved upon. Describe the item deficiencies and what could be done to improve on the ergonomic design to reduce injury potential or increase efficiency.
