Relative Influences of Biology and Culture shift over the life span (Contextual). Biological Abilities weaken with age, but cultural supports could help compensate with the loss.
Development Involves changing resource allocations (involves Growth, Maintenance, and regulation of loss). Resources may be used for growth, for maintenance or recovery, or for dealing with loss when maintenance and recovery is not possible.
