Technology has taken our senses to a whole new level. Just look at the difference between the average 18 year old and the average 58 year old out there today. What's considered normal technology to an 18 year old nowadays is way beyond what *most* people born 40 years later can begin to understand.
Usually people don't know this, but our most memorable sensations come from our olfactory senses (our smelling ability/recognition). Just remember that smell that takes you back to your grandmother's/mother's kitchen way back when. They say a picture is worth a thousand words, but I think a smell is endless when it comes to emotions.
The tech world has tried to introduce this sort of thing in the past, but I think the money just wasn't there since the technology is so expensive.
I know it's probably way out in the future....but how far, and how successful do you think something like this would be?
