The first ICU patient in Italy was a 38-year old man who ran two half marathons a week before hospitalization. Iranian 22-year old futsal national team member passed away as well. Many young people have damaged lugs for life after surviving on ICU. I am not sure why people downplay the potential of damage for younger and healthier people just because it predominantly targets old and sick people. The virus might also mutate to more deadly strains.
The risk is already not that low at 55-65. These are people that are working and thus very likely to catch it.
