This definition can be contrasted with that proposed by life-span developmental psychologists: Development is a life-long process beginning at conception and ending at death (Honzik, 1984, p. 309). Development is thus extended to include the whole of life.
A cockroache can live up to 10 days without its head. In fact it doesn't die of suffication but of dehydration.  a cockroach can live up to a week without it's head because â¦it's brain is in its body. 1 person found this useful.
So what is the truth? A cockroach can usually live for about 7 to 10 days without water, but can go for at least 30 days with no food before it dies. Therefore, it is almost impossible for a cockroach to starve to death unless it is enclosed or trapped. This is because of its uncanny ability to eat almost anything in its environment.
