They’re not all the same. Some see better than others, some smell better, some hear better. Maybe it has something to do with how rotten they are before the virus starts puppeting them. Not sure. Anyway, you can’t make assumptions.
Keep as clean as you can. Use rain water. The stronger your body odor, the more likely you’ll be some zombie’s lunch.
Go out at night. You can’t see very well in the dark, but you can see better than the best of them. Take some flares. You get made, light one, toss it, then run in the other direction.
