If we wish to colonize another world, finding a planet with a gravitational field that humans can survive and thrive under will be crucial. If its gravity is too strong our blood will be pulled down into our legs, our bones might break, and we could even be pinned helplessly to the ground.
Finding the gravitational limit of the human body is something that's better done before we land on a massive new planet. Now, in a paper published on the pre-print server arXiv, three physicists, claim that the maximum gravitational field humans could survive long-term is four-and-a-half times the gravity on Earth.
Or, at least you could if you are an Icelandic strongman – and Game of Thrones monster – who can walk with more than half a metric ton on your back. For mere mortals, the researchers say, it would need to be a little weaker.
[...] For the maximum gravity at which we could take a step, the team turned to Hafþór Júlíus Björnsson, an Icelandic strongman who once walked five steps with a 1430 pound log on his back, smashing a 1,000-year-old record[*].

What's the Maximum Gravity We Could Survive?

At that point it really becomes feasible to exploit resources that are easily accessible from zero-g, the asteroid belt for instance. And once sufficient capital is built up there, a sort of mega-HOME could be built, large enough to be pretty darn self-sufficient.
It would not go at a La Grange point, but into it's own solar orbit, and would be able to shift that orbit, even to escape it over time, if desired.
