Some wines will last longer than others after opening, but generally speaking they all deteriorate, mostly because of the oxidation that occurs after exposure to air. Before a bottle is opened, there is little empty space in the bottle. After opening, however, the space obviously increases, and the wine mixes with air as the wine is poured out.
I recommend that you shouldn't hold onto a bottle of wine for more than a day or two. And instead of merely sticking the cork back into the neck, you might want to buy one of those pump reclosures. They suck most of the air out of the bottle, which preserves the wine a bit longer.
Further, for everyday drinking you might consider buying bulk wines in boxes instead of large (3- and 4-liter) jugs. The boxes have collapsible bladders inside that prevent air contact as the wine is consumed. The quality of the wine is preserved much longer.
