Jatin Prasad was born in Allahabad in 1938, on a date not divisible by 2, 3, or 5, and in a month that does not contain the letters "e" or "i". When does he become one year older?
1939 on the same date & month (not divisible by 2,3 or 5 & in the month not containing the letters "e" or "i")
I always wait unit you're off guard or get older so you can become easier to attack. Once your body is weak, I strike inside you and try to kill you. What am i?
