I have been a critic of my government policies and communication for just this reason. There has been a huge focus on death rate and policy based on the death rate. The governments focus on the death rate lead to embolden youth who “won’t die” so they gather and are willing to ignore protocols. Only last month when covid in youth was spiraling out of control did they mention long term effects.
Internal scar tissue can and does get reabsorbed over time by the body. Not all scars and not every time but if we are going to split hairs, a scar is capable of being reintegrated into the tissue to the point that it is no longer detectable. A scar is unlikely to ever fully disappear but scar tissues go through various levels of remodeling and in many cases small scars can become undetectable over periods of time in various levels of tissue.
