  • In an age of global strife and climate change,

  • I'm here to answer the all important question:

  • Why is sex so damn good?

  • If you're laughing, you know what I mean.

  • Now, before we get to that answer,

  • let me tell you about Chris Hosmer.

  • Chris is a great friend of mine from my university days,

  • but secretly, I hate him.

  • Here's why. Back in university, we had a quick project

  • to design some solar-powered clocks.

  • Here's my clock.

  • It uses something called the dwarf sunflower,

  • which grows to about 12 inches in height.

  • Now, as you know, sunflowers

  • track the sun during the course of the day.

  • So in the morning, you see which direction the sunflower is facing,

  • and you mark it on the blank area in the base.

  • At noon, you mark the changed position of the sunflower,

  • and in the evening again, and that's your clock.

  • Now, I know my clock doesn't tell you the exact time,

  • but it does give you a general idea using a flower.

  • So, in my completely unbiased, subjective opinion,

  • it's brilliant.

  • However, here's Chris' clock.

  • It's five magnifying glasses with a shot glass under each one.

  • In each shot glass is a different scented oil.

  • In the morning, the sunlight will shine down

  • on the first magnifying glass,

  • focusing a beam of light on the shot glass underneath.

  • This will warm up the scented oil inside,

  • and a particular smell will be emitted.

  • A couple of hours later, the sun will shine

  • on the next magnifying glass, and a different smell will be emitted.

  • So during the course of the day, five different smells

  • are dispersed throughout that environment.

  • Anyone living in that house can tell the time

  • just by the smell.

  • You can see why I hate Chris.

  • I thought my idea was pretty good,

  • but his idea is genius,

  • and at the time, I knew his idea was better than mine,

  • but I just couldn't explain why.

  • One thing you have to know about me is I hate to lose.

  • This problem's been bugging me for well over a decade.

  • All right, let's get back to the question of why sex is so good.

  • Many years after the solar powered clocks project,

  • a young lady I knew suggested maybe sex is so good

  • because of the five senses.

  • And when she said this, I had an epiphany.

  • So I decided to evaluate different experiences I had in my life

  • from the point of view of the five senses.

  • To do this, I devised something called the five senses graph.

  • Along the y-axis, you have a scale from zero to 10,

  • and along the x-axis, you have, of course, the five senses.

  • Anytime I had a memorable experience in my life,

  • I would record it on this graph like a five senses diary.

  • Here's a quick video to show you how it works.

  • (Video) Jinsop Lee: Hey, my name's Jinsop,

  • and today, I'm going to show you what riding motorbikes

  • is like from the point of view of the five senses. Hey!

  • Bike designer: This is [unclear], custom bike designer.

  • (Motorcyle revving)

  • [Sound]

  • [Touch]

  • [Sight]

  • [Smell]

  • [Taste]

  • JL: And that's how the five senses graph works.

  • Now, for a period of three years, I gathered data,

  • not just me but also some of my friends,

  • and I used to teach in university, so I forced my --

  • I mean, I asked my students to do this as well.

  • So here are some other results.

  • The first is for instant noodles.

  • Now obviously, taste and smell are quite high,

  • but notice sound is at three.

  • Many people told me a big part

  • of the noodle-eating experience is the slurping noise.

  • You know. (Slurps)

  • Needless to say, I no longer dine with these people.

  • Okay, next, clubbing.

  • Okay, here what I found interesting was

  • that taste is at four, and many respondents told me

  • it's because of the taste of drinks,

  • but also, in some cases, kissing is a big part of the clubbing experience.

  • These people I still do hang out with.

  • All right, and smoking.

  • Here I found touch is at [six], and one of the reasons

  • is that smokers told me the sensation of holding a cigarette

  • and bringing it up to your lips is a big part of the smoking experience,

  • which shows, it's kind of scary to think

  • how well cigarettes are designed by the manufacturers.

  • Okay. Now, what would the perfect experience

  • look like on the five senses graph?

  • It would, of course, be a horizontal line along the top.

  • Now you can see, not even as intense an experience

  • as riding a motorbike comes close.

  • In fact, in the years that I gathered data,

  • only one experience came close to being the perfect one.

  • That is, of course, sex. Great sex.

  • Respondents said that great sex

  • hits all of the five senses at an extreme level.

  • Here I'll quote one of my students who said,

  • "Sex is so good, it's good even when it's bad."

  • So the five senses theory does help explain

  • why sex is so good.

  • Now in the middle of all this five senses work,

  • I suddenly remembered the solar-powered clocks project

  • from my youth.

  • And I realized this theory also explains why Chris' clock

  • is so much better than mine.

  • You see, my clock only focuses on sight,

  • and a little bit of touch.

  • Here's Chris' clock.

  • It's the first clock ever that uses smell to tell the time.

  • In fact, in terms of the five senses,

  • Chris' clock is a revolution.

  • And that's what this theory taught me about my field.

  • You see, up till now, us designers,

  • we've mainly focused on making things look very pretty,

  • and a little bit of touch,

  • which means we've ignored the other three senses.

  • Chris' clock shows us that even raising just one

  • of those other senses can make for a brilliant product.

  • So what if we started using the five senses theory

  • in all of our designs?

  • Here's three quick ideas I came up with.

  • This is an iron, you know, for your clothes,

  • to which I added a spraying mechanism,

  • so you fill up the vial with your favorite scent,

  • and your clothes will smell nicer,

  • but hopefully it should also make

  • the ironing experience more enjoyable.

  • We could call this "the perfumator."

  • All right, next.

  • So I brush my teeth twice a day,

  • and what if we had a toothbrush

  • that tastes like candy,

  • and when the taste of candy ran out,

  • you'd know it's time to change your toothbrush?

  • Finally, I have a thing for the keys on a flute or a clarinet.

  • It's not just the way they look, but I love the way they feel

  • when you press down on them.

  • Now, I don't play the flute or the clarinet,

  • so I decided to combine these keys with an instrument I do play:

  • the television remote control.

  • Now, when we look at these three ideas together,

  • you'll notice that the five senses theory

  • doesn't only change the way we use these products

  • but also the way they look.

  • So in conclusion, I've found the five senses theory

  • to be a very useful tool in evaluating

  • different experiences in my life,

  • and then taking those best experiences

  • and hopefully incorporating them into my designs.

  • Now, I realize the five senses isn't the only thing

  • that makes life interesting.

  • There's also the six emotions

  • and that elusive x-factor.

  • Maybe that could be the topic of my next talk.

  • Until then, please have fun

  • using the five senses in your own lives

  • and your own designs.

  • Oh, one last thing before I leave.

  • Here's the experience you all had while listening

  • to the TED Talks.

  • However, it would be better if we could boost up

  • a couple of the other senses like smell and taste.

  • And the best way to do that is with

  • free candy.

  • You guys ready?

  • All right.

  • (Applause)
