are there only 5? we may have thousand senses which we are using unconsicously.. which we have never discovered so far.. by biology or science. how hard is it to put a small magnet in our body.. may be we do have a direction sensing device in our body. it can be anywhere.. head neck torso.. it can be so small just a few iron molecules and a few nerves going out of it.. when our body has a gyroscope in our head to find balance.. why not magnet.. see any lame person knows only 5 senses he doesnot know that he can sense balance..gyroscope is out of conscious control. how do i sense prana and all.. we may have devices which can intercept and network thoughts of other people.. sense that someone is lookin at u even when u dont see them..offcourse we have timers.. gravitation sensors? not only of earth but that of moon and other plants very sensitive gravitation sensors? thats why moon affects so many peoples moods, thats why astrology ?sharks have electric sensors.. we may have too.. and 1000 types of software making use of this hardware.. sharks determine the direction of prey by calculating the delay betwen the smell reaching different sensors...so many senses and so many applicaitons.
