Age is a disease. That’s Dr David Sinclair’s point. It has all of the symptoms of a disease, and the only reason that it’s not classified as a disease is because everyone suffers it.
So, how does it work? Cells are allocated to certain tasks within the body at birth. During life, they die off, and are replicated. It’s during that process that the ageing occurs. The body needs to get rid of the dead cells (senescent cells), and the replication needs to be prefect. Often the reproduction is flawed, like photocopies of photocopies, and cells become less effective at their job.
The body also needs to rid itself of the senescent cells, and there is an effective process for doing that, called autophagy, which though our lifestyles we can either help, or hinder.
Now, the Dr Sinclair is talking about slowing and even reversing the ageing process.
The accumulation of senescent cells inhibits the body’s ability to create good replicas of cells, which is why it’s so important to get rid of them. More senescent cells equals faster ageing.
The environment factors that influence our ability to produce healthy cells are exercise, diet, and supplements.
Adversity builds strength. Our modern lifestyles protect us from hunger and cold. Without these adversities, our bodies become complacent, and less effective.
Deficiencies in various vitamins will also accelerate the ageing process.
