This issue nibbled at my brain a lot whenever I think of a Z Apocalypse.
The person with cardio issues (unable to breath right after walking or running, unable to even run because of heart palpitations and pain, anxiety.. etc) You do not need to have serious heart issues. You do not need to be overweight. Cardio issues can occur due to how you probably live your life. Unhealthy diet, not a lot of exercise. You'd know you have cardio issues when you can't even blowing into a bag.. your capacity in doing so will betray you.
Now this can be you, while you are trying to survive the Infection. You need to stay with your team and keep up with them as you run away from the Infected or traveling around looking for a better shelter for you and your team. There is only one issue here, you will slow them down. You will either end up rushed by a horde because you're damn slow, or they will end up leaving you behind.
You don't know if the team you're gonna end up with will be taking care of you because it's not like you are participating in a scavenger hunt event. This is the Apocalypse and human nature is evil no matter how human we might appear to be when surrounded by zombies. People will think of themselves first before anyone else.
Now, i'd like it if we can discuss ideas and maybe come up with something to prepare us if this ever happens to us. Bring along with us Vitamins for example.. energy drinks (but they might not be good for some of the bad cardio survivors) One thing is sure, we need to eat healthy and exercise that way we won't be put in a position where we have to stop everyd 5 seconds to breath because we can't keep up with the team. That way even if there will be no Z Apocalypse, you'd be living a better life.
... Some people out there will continue living their lives the way they see fit. So what would you do, if one of your teammates cannot run, cannot walk fast because of bad cardio. Would you abandon him there? One thing is sure, you don't wanna be the Nurse when you're battling zombies because it is only a matter of time before they catch up on you and your teammate. But then... he could be your brother, he could be your husband, he could be anyone you don't wanna leave behind...
I agree, I would like to think that I would do everything in my power to save the group from danger but thinking realistically if there was a situation where one person's lack of fitness would get the entire group killed I would probably sacrifice the one to save the many, and it's a little scary to think that people probably will be forced into those situations once the zpoc hits.
One thing I wanted to touch on from the earlier posts, I see a lot of people talking about doing sit ups and push ups and those are good exercises but they are for the wrong muscle groups. In the zombie apocalypse the cardiovascular system will be absolutely key to survival but push ups and sits ups aren't going to do anything to improve it. Go for a run or a bike ride, hop on the elliptical machine, even taking the stairs instead of the elevator will contribute to boosting your cardio.
my opinion is, when outbreaks first happen nobody really realizes it until its to late, so most of those people would be gone. However, if I ran into someone that had issues then I would help them out because you never know what type of skills they have (they could be a doctor). Also the more in your party of survivors the better chance of living everyone has.
Just for the record i want to say that a member of my party gets bit they can stay as long as there in front of everyone, that way when they do turn you wont be surprised and you can deal with that zed.
