  • Discuss our fast paced society and the rising cost of shipping. Discuss the impact of visual appeal.
  • Talk about the fast paced society. Ask students about environmental and human impacts, both positive or negative, when a change takes place. Use the automobile as an example.

    14. 14. Over the past 100 years there have been many innovations to the toothbrush: Ergonomic handles, spinning heads, and improved bristle configurations to name a few. A pioneer in this transformation was Dr. Robert Hutson, a periodontist from San Jose, California. Hutson invented the first toothbrush with soft end-rounded nylon bristles.
