Seriously, what would ALL students do without you, Sal? I am 46 years old and just started college.

I have had friend after friend (spread across the country) direct me to your youtube videos. Oh. My. Gosh. YOU are the only way I can understand ANY chemistry, anatomy and physiology, MATH... you name it!
I told my high school daughter about you. She says, "Duh. I know that. How do you think I learn all this stuff.."

All us old ladies have a huge crush on you, Sal, and we have never seen your face. THANK YOU SO VERY MUCH FOR THE WONDERFUL WORK YOU DO!!! YOU ABSOLUTELY MAKE LEARNING FUN!!!

Sincerely,
J.
