ELI5: What is the reasoning behind the US congress having no term limits?

I'd also really love an explanation as to *why* they get healthcare coverage for life when military members etc don't?

In my mind, the position of congressman/senator is a public service, not a right of passage to comfortability and wealth.

The *President* didn't even have term limits for almost 200 years. The reasoning behind that is that the President is 1/3 of the government by himself, as well as the commander in chief of the military. That power can be abused, especially by a president who stays in office for many years and uses his power to weaken political opponents.

By contrast, a Senator or Congressman is just 1/100 or 1/435. Even the most powerful of them can't really do much on their own. 

I personally don't believe in congressional term limits, because the people should take the responsibility of monitoring their representatives and replacing them when necessary. Term limits are a lazy and half-assed way to avoid that responsibility.

Lastly, former members of the military do get lifelong healthcare if they're wounded in action. Additionally, anyone who retires from the military can stay on the government's plan for cheap.
