How much gravitational force does the Sun exert on you? Do you feel any of it?
A constant gravitational field doesn't change anything - everything is accelerating the same amount, in the same direction. What can cause problems is the difference between the gravitational field at two different points (for example, when a planet gets too close to a star, it can be torn apart due to the force exerted on the near side being much greater than the force exerted on the far side). But this isn't the same as the overall strength of the field, and a sufficiently large black hole could have a very survivable field gradient at the event horizon.
