Until EVERYONE EVERYWHERE is blessed with COMMON SENSE, A DESIRE TO LIVE AND A DESIRE TO NOT HARM we are doomed.
There will always be the selfish who don't give a rat's a** about anyone or anything. They are the spreaders of death forever because they just don't CARE.
Vaccines won't help if many don't get them. So we float on a sea of death surrounding us because so many homo saps are selfish saps. No way out. No exit. Well death of course is the FINAL exit.
