At what age should you stop riding a bike?

I'm curious, at what age does one typically decide to hang up their bike helmet and retire from cycling? Is there a universal consensus on this matter, or does it vary depending on individual fitness levels, personal preferences, and perhaps even regional customs? I'm eager to understand the rationale behind this decision-making process and whether there are any potential health benefits or drawbacks associated with continuing to ride a bike well into one's later years.
