Rule #9: Stimulate more of the senses.

Our senses work together so it is important to stimulate them! Your head crackles with the perceptions of the whole world, sight, sound, taste, smell, touch, energetic as a frat party.

Smell is really important to business. When you walk into Starbucks, the first thing you smell is coffee. They have done a number of things over the years to make sure that’s the case.
The learning link. Those in multisensory environments always do better than those in unisensory environments. They have more recall with better resolution that lasts longer, evident even 20 years later.
