During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ... At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase.

Here's an idea:
"Do mice live longer when they are fed high-sugar diets." Collect two groups of young mice; one that will be fed low-sugar diets, and one will be fed high-sugar diets. Keep them on those respective diets for as long as they live. Research previous studies that have been done before and make a hypothesis as to what will happen in yours. Observe their health throughout the experiment. Make sure you count how long each mice lives. Determine an average count of years/months for both groups, and come to your conclusion.
No idea if this was the sort of answer you were looking for, but I hope this helps.
