Dog
Dog ownership correlates with measurably improved cardiovascular health, reduced depression rates, and increased daily physical activity. Dog owners walk an average of 22 additional minutes daily compared to non-owners, primarily because dogs require walking regardless of weather conditions or owner enthusiasm. The social facilitation effects of dog ownership reduce loneliness, as dogs serve as conversation initiators and community connectors. Studies indicate dog owners have a 24% reduced risk of all-cause mortality.
Sonic
Sonic games provide cognitive stimulation through hand-eye coordination challenges and problem-solving elements. Extended play sessions may improve reaction times and spatial reasoning. However, the physical health implications of remaining stationary whilst manipulating a controller are, at best, neutral. Sonic cannot compel you to leave the house, cannot demand walks in inclement weather, and cannot guilt you into exercise through the application of pleading eyes. He is, fundamentally, an enabler of sedentary behaviour.
