Not really.
I have no idea if the guy was or was not using steroids and whether or not he could use them later to bulk up or not is not really that relevant.
Read the link. First, 6 weeks in ICU means you have a serious problem and your body will doing things like convert muscle to energy to fight the infections -- immune system gets priority. Additionally, with a tube down his throat he apparently was not getting the same caloric intake, so again would see significant weight loss.
But perhaps the more import aspect is his reporting of the loss of lung capacity and the question of if that will come back or not. If not, looks like that will be something of a life style change for him.
The clear message here is that "if I will not die there is nothing to worry about" is just the wrong view. Point being, just thinking about risk of death is ignoring known facts about the virus and disease so setting oneself up for some potentially disappointments about choices in hind sight.
Make informed decisions about the risks you think apply to you and what you willing to accept in terms of consequences if you do get infected. That said, I will also agree that we probably have more than one person reading this post -- or at least on TER -- that has been infected and never knew it.
That's a large spectrum. Try to know where you personally fit and then try to make the best out of the life we get to live today. I don't think anyone should be just "laughing" the pandemic off or making fun of those that are being more cautious. I do say that as someone who saw a provider on Saturday and then went out on Sunday, OTC, for a walk around the neighbor and then to grab something for dinner to take back to the apartment to eat with her. So by the same thinking, people should not be making more of those who don't think the risks they face, personally or create for others, are sufficient to make a big life style change.
What do I think would be a good thing to note? Those in the medical profession working directly with treating these infected patients are exposed to WAY more virus than any of us are. That does matter a bit. If rather than being a nurse he was doing something else and his exposure was from seeing a provider would he had had as bad of case? We don't know but that doesn't seem too far fetched.
