Good on you @ddon - It is so important to be aware of your normal 'rates' for everything, as your baseline reference.
My husband's resting pulse is well below 50 (he was a very fit athlete/triathlete for 65 years - but age has finally caught up with him now at 83.) Looking at it statistically - that is a pretty well a 30% increase of your 'normal' heart rate, so applied to a regular person, that would put theirs up at 100+ and THEY would be concerned too .... and keep in mind that body temp only needs to go up .5˚+ to be worrisome!
All the best xx
