As we get older it is our short term memory that fades rather than our long term memory.

Neurogenesis continues throughout life and we have the capacity to establish new neural pathways and strengthen existing ones.

Plasticity is an intrinsic property of the human brain and represents evolution's invention to enable the nervous system to escape the restrictions of its own genome and thus adapt to environmental pressures, physiologic changes, and experiences.
