I can understand having scuzzy bacteria-ridden dishes getting one sick, but what about bacteria in the rest of the house? Does anyone actually ever really get sick from bacteria on bathroom counter tops, or coffee tables? We get sick from viruses from outside the house. Why the rant over anti-bacterial this and anti-bacterial that? Seems like with bacterial resistance these days it's a good idea to leave these little harmless friends alone.

Suppose i am travelling on a photon , sitting on it , now as my speed is equal to C , the time gets dilated for me and becomes INFINITE , what does this actually mean ?

Does it means that TIME does not exist for me , no hours, no minutes & no seconds with respect to a stationary observer , but if i have an observer besides me sitting on a photon with a watch which is moving with speed c then the intervals of time will exist for me
