Why can't we live on Saturn or Jupiter?

First, gravity. The increase in weight on Saturn is negligible, only 106.4% of your weight on Earth. So, on Saturn, a 100 pound person would weigh 106.4 pounds. On Jupiter, however, the increase is 236.4%, so you would weigh 236 pounds.
We don't even know if Jupiter has a solid surface! The outer areas of Jupiter are extremely cold. Lower down, when they become about room temperature (around 70 degrees F) the atmospheric pressure is ten times greater than that of Earth. Saturn also may not have a surface, and in the area where there could be one to speak of, winds get up to 1800 km/hour.
Finally, the atmospheres of these planets would not support life that needs oxygen or carbon dioxide. The atmosphere of both planets are mostly hydrogen and helium.
Keep in mind that for billions of years, oxygen was not a significant part of Earth's atmosphere. It took eons of simple life giving off oxygen as a waste product before there was enough for more advanced life to evolve here.

Or maybe Jupiter. From;
http://en.wikipedia.org/wiki/Colonization_of_Jupiter#Potential_for_colonization
"The planet itself could be the site of airborne colonies such as floating cities, assuming the radiation and gravity issues in traveling to and from the atmosphere are properly addressed. Jupiter has an atmospheric depth with the same pressure as Earth sea level, where there is also a blue sky, though it is colder than on Earth; further down, Jupiter has an atmospheric depth that is the same average temperature as the surface of the Earth, where the pressure is about eighty bars. Orbiting colonies can also exist, using Jupiter's natural gravity from a distance, thus equaling Earth's. The bases would need to withstand radiation from all angles. This type of structure could also serve as a dock for ships.
However, even here, airborne colonies such as floating cities would be unlikely, because Jupiter has a surface gravity of around 2.4 g near the surface of its atmosphere, as well as massive wind currents that may prove hazardous to a floating colony. One significant challenge to overcome in colonizing the planet would be the intense radiation in the planet's magnetosphere. Hydrogen and helium isotopes are relatively plentiful in Jupiter's atmosphere. Because the atmosphere is dominated by hydrogen, however, any leak of an oxygen atmosphere or a liquid oxygen bipropellant would present a significant risk of catastrophic explosion."

We couldn't live on Venus either. Venus has an extremely high atmospheric pressure at its surface (about 90 times that of the Earth), and not to mention its atmosphere consists mostly of carbon dioxide which we cannot breathe.
Oh, and why would you? There is a giant storm blazing on Jupiter anyway, so you would have to stay indoors all the time..
