 Teresa and I'm back with another video, but this time I'm actually gonna have my dear friend who's begging and pleading me to do this video. I'm gonna have him do it. He's really cool and I hope you like him, so I'll hand the camera over to him in a second. Hopefully he's not too weird, but in the meantime, if you were interested, you could check out my personal channel, which is up will be listed in the description below. Thanks so much and I hope you enjoy my friend's company. Hello, my name is Dr. Psychology. You can call me Dr.ology for short. I received a letter in the mail today from a friend of mine. Let's open it. Dear Dr.ology, whenever I come to your house, it always smells like old spice. I can never smell what my house really smells like at home Why is this? Please help. Love John. Well John, you see you're not the only one with this problem. I can't smell my own house either. I smell nothing and then gets you thinking, is nothing a smell? No. And you might be thinking to yourself. You see, the smell would not derive from a stink because stentions such as dirty laundry or bad hygiene is a temporary smell more than likely, which can completely go away. And your whole entire house isn't a temporary smell. Your nose is subject to subtle changes. So it detects these smells that are subtle and it intakes them at a fuller force than a smell that you've been around for a longer period of time. In a way, you can think of these smells as almost a kind of threat or a surprise if it's a different kind of smell. Your nose will tend to smell it more strongly than other scents. A psychologist who did an experiment, the psychologist's name is Pamela Dalton. And Pamela Dalton took a few people, gave them a piney kind of scent to put in their room for a long period of time. And after about two weeks, the people claimed to not be smelling it anymore or the scent was going away. The scent was still there. They became almost desensitized from the smell because it's been around for such a long period of time. And it's not your nose that's in charge of this. It's actually your brain. You see, your brain stores memories and memories can be triggered by different smells. So if you smell something such as a scented candle, your brain will take that into account if it keeps being used over and over day by day, your brain will just say, I don't need to keep focusing on this smell. It's nothing new. It's nothing exciting. So goodbye. In a way, I guess you can say it's kind of good for your brain to be nosy. This kind of event or occurrence is called sensory adaption. Sensory adaption is when you smell something and your brain adapts to that smell. And you might also be thinking to yourself, well, then how can I smell what my house smells like? Because I want to smell it. Well, did you know that it's possible? I went on a fishing trip not too long ago and I was just catching fish for a week. I came back to my house and it smelled. It had a smell and it just hit my nose and I was like, whoa, my house has a smell. So turns out you can smell it, but you just have to be absent from the smell for a certain period of time so that your brain has a chance to say, this is a new smell again. It's a good thing that your brain does what it does. Just remember if you get scared because you can't smell the smell of your house and you think you might be suffering from nose blindness, just remember that it's completely normal and it happens to everyone and it's gonna be okay. But John said that my house smelled like old spice. Oh, oh my goodness. Oh my, oh my goodness. I forgot these were even here. Look at all this old spice and it looks like I'm running out of time. Catch you next time. Where is the button on this thing?
