if you were in 28 days later how quickly would you be dead based on your area and what would your survival tactic be?
i live in south london , id probably run to my local hardware store/ supermarket and board up my house and get a load of food, bottled water, and batteries if i couldn't go to the countryside. i'd board up my house and fill up all baths and sinks with tap water before it cuts off and hope for the best - maybe after the apocalypse has settled down i may move outside.
my extended family lives in the rural countryside so id probably drive over there with food / water and do the same thing for higher chance of survival.
