"....beta receptors in the heart are not of the same type as those in the organs... what?"
Oh I´m glad, quite glad. I can´t say how much because I wouldn´t like the idea that the beta receptors (whatever they are doing) in my heart are the same as in my rectum I guess. ;-)
Hm, what is it about the stuff that the heart is the home of the soul??? Wow, the soul has to share her place with a lot of other stuff, blood, beta receptors, venes and so on and so on.
Uaaah, my braincell gives me a lot of quite disgustingly imagines, aarrrrgh T_EYLA!!!
