11/7/11 - If you had to give up one of your 5 senses, which would it be? >> I'd give up my sense of smell because i find the other 4 too valuable. I like tasting a good home cooked meal my mom makes. I like hearing my friends' and families' voices and the jokes and stories they tell or questions they ask me. I like seeing nature and all it has to offer. I don't think i'd be able to see the inside of my eyelids for the rest of my life. I like feeling the hugs from loved ones and the handshakes of friend >> > **PsychSim 5: THE AUDITORY SYSTEM **This activity explores how we hear and how the physical nature of the sound wave determines the qualityof the sound experience. > **The Auditory System ** > >  What are the four tasks of the auditory system? > 1.

<span style="font-family: 'Times-Roman','sans-serif';">11/8/11 <span style="font-family: 'Times-Roman','sans-serif';">- I've had a recent psychic experience. Last week I went to BJs with my mom and I saw this kid working at the door checking the receipts. As soon as I saw his face, I recognized him. I knew him from somewhere, but I couldn't remember exactly: drama fest? school? AP prep sessions? I had no idea. So I made sure that when I left BJs, I notcied his nametag. His name was Raul. And so, I went home, typed in Raul in the search box on Facebook and there he was! Raul V....something or other. He graduated MHS in 2009, but that would mean I were a freshman when I had met him. So I thought back to all of my classes freshman year and i got it! He was in my chorus class freshman year. So i was satisfied that I had figured out where I knew him from, and I logged off Facebook and went on with my life. The next day, I went on Facebook and had a friend request and it was from him!!! I wasn't wearing a nametag at BJs, I never even held a conversation with him before in my life! So to this day, I'm confused on how he could've found me. So i think I'm kind of psychic :D
