Yes, but these are not seven "causes." All seven listed here are symptoms, or are all being caused by what I believe is one culprit = Radiation Exposure.
Fact: Tiny radioactive particles from space called muons, which our atmosphere fails to protect us from, are raining through your body as you read this at rate of over a 100 hits per minute, per square foot of surface area, 24 hours a day. 6,000 hits per hour, 144,000 hits per day!
My theory: These fast moving particles pass through our bodies like cellular sized supersonic bullets smashing through our DNA stands, "causing" mutations, cellular loss, cancers, tumors, in fact all the symptoms we know as aging and death.
The Cause: As these atomic particles smash through our DNA library of how you look, how your cells function and replicate, those damaged strands weaken your genetic code, reading incorrectly and make the next you different by increments that are both gradual and accumulative.
Each organism on this planet suffers from accelerated aging, from plants to animals, insects and humans.
How do I know this? Putting the evidence together: This rapid aging speeds up for astronauts that work completely outside out protective layer. NASA is working right now on ways to protect them from this.
However organisms that live at the bottom of our oceans, which have more protection from these muons, grow larger and live much longer than their shallow water relatives.
Like the deep ocean giant tube worm:
The challenge: There is much more to be seen on this if one is willing to look. This theory answers so many questions, from aging to why all things decay. The evidence is in front of us: It is my belief that our potential lifespan and quality of life is 1/10th what it would be if we were to find a way to increase our atmospheric protection by a factor of 6-7 times.
I have been privately studying this topic for all my life. The advantages of increasing the protective layer around our Earth cannot be measured, and I can think of no scientific research more important for the advancement and survival of our species than this.
