This was me as an embryo. I have developed my eyes, fingers, and most internal organs, but they are not yet fully functional.
This is me as a newborn. I have many reflexes such as the Palmar reflex, which is where I close my fist around anything placed in my hand. My growth slows during ,y second year.
These are twin toddlers that I babysit. They are about 3.5 years old, so they are starting to develop a conscious memory.
This is me in adolescence, but I had already went through puberty. Maturation of the frontal lobe lags behind the lambic system.
This is me when I am at old age. I will have a decay of fluid intelligence, and am more likely to get diseases like Dementia or Alzheimer's.
