Opinion: Neither is a much better job than the other, so, it’s a tie. The older we get, our minds and bodies gradually return to the first stages of infancy. Merely, two differentiating factors are: 1. their opposing sizes; babies/kids are easier to maneuver/ carry, and 2. our elder speak words clearly, versus learning to speak by mimicking sounds. Aged people are also adorable and just as sweet! Essentially, for those passionate about helping others, as I do myself, surprises, excitement, and the thrill rush from old people and babies/kids spreads gracefully throughout our environment, stuffing us with laughter and replenishing our bones with great nourishing joy! At least that’s why I can’t pick one over the other.
