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.
I have heard many different opinions on how old a cockatiel life span is and I'm as in the dark as I have ever been on the matter, and my bird Russ is going on 16 now.I'd love to have some frim idea so that I don't receive the shock of my life one morning when I take his covers off.ho knows, he may be hanging around for another 15 years. My tiels are only 4 years old right now, and I try to feed them the best diet possible. With a good diet (seeds, pellets, veggies, whole wheat bread, rice, boiled egg once in a while, etc.) cockatiels can live long and healthy for a long time.
