Pay attention to your health at all times. If you fail in health, you won’t be able to do anything. It’s not like losing a weapon where you have to take some chances to find it and get it back. Once your health is gone, you have nowhere else to go and nothing else to do. In order to avoid health problems, make sure that you don’t take on too much damage. You have to be very selective with your battles. If you select a battle, take a good position so you will limit your damage while still having an opportunity to inflict as much harm as possible.
You can also lose health by falling off buildings, mountains, sheds and any other high object. This might sound clumsy, but that’s not the issue. The issue is that if someone is trying to punch, stab or shoot you, then you might not have as much room as you think. If you end up falling, you can break a bone or do other damage. It will be necessary to go to higher elevations at certain points in the game. Just don’t go out of your way to go to higher elevations. You might be tempted to take in the view, and the surroundings might seem peaceful and safe, but that’s rarely the case in the Mojave Wasteland. Someone is almost always lurking, waiting for the right time to strike. You don’t want to be the target. In order to heal, you’re going to need to pay for treatment or sleep it off.
Radiation is another factor. In case you didn’t already know, human beings and radiation don’t mix very well. The problem here is that when you’re in the Mojave Wasteland so you’re going to be exposed to radiation. The good news is that there is a way to deal with this problem. The best way to deal with radiation poisoning in Fallout: New Vegas is to use RadAway. All your radiation-poisoning problems will be a thing of the past. If only we could have RadAway in the real world.
