If humans were ectotherms would we live much longer?

Mammals are endotherms meaning we can expend energy to heat our own bodies. This requires a lot of eating and shitting.

Reptiles like turtles dont have this luxury yet they can live over a hundred years and they're just crap little animals. If crap little mammals like rodents only live a fraction of what a human's lifespan is. Does that mean if we were ectotherms we could potentially live hundreds of years?

Srs reply, we wouldn't be able to power our brains. We'd be like Discworld trolls that can only do math when the outside temperature is exactly right.

OTOH the combo of ectotherm + bird lungs lets animals become fucking huge, so that would be cool.

Probably. Metabolism Determines our lifespans.

We'd also have trouble adapting to colder climates and living in colder areas of the world.

Half of our lifespans would have been spent hibernating most likely.

We would also have a harder time sailing over oceans in barges till the industrial age.

Our social structure would be a lot different, and maybe we wouldn't have as much need for physical contact.
