Not sure about dying but here is my personal experience. I am far from being anywhere close to a real cyclist. Still I used to ride a bit too much and at some point my resting heart rate dropped down to below 45. At this point I got really scared and cut down on my cycling. Now it is more like 50 so it is ok. Funny thing I also swim a lot but it does not seem to affect my heart rate as much as cycling has.

Unless you have a serious heart defect or are using certain PEDs there's no reason to be scared or a resting heart rate of 45.

  At that point 45 was upper limit of my RHR. The lowest short time span value that I remember was 38. I just did not like it at all. Curious if I get downvoted for this as well.

    There's no medical reason to dislike a RHR of 38.
