Answer:
There are many serious diseases that can affect us today. There are diseases like MCS, Hypertension, Parkinson's, and many more. These are all similar in that they affect some of the body's most important processes that allow us to carry on our day-to-day. Cardiovascular disease is the blockage of the arteries and veins due to obesity or unhealthy habits, it is a very hard disease to overcome because it has a lot to do with the only way to keep the body functioning. As new technology is being invented and distributed, medical treatments will slowly improve. I believe that these diseases will eventually be cured, but I think it will take a lot more time.
hope this helps:)
