I buy into that, however smoking is a lifestyle. The sudden toilet paper
shortage, here last year, really opened my eyes. When the supply chain
sputters for more than two months, people who are dependent on
pharmaceuticals will start to die in large numbers.
Those with better adapted genetics won´t...yet. Darwin and all. Everything
one thinks they know won´t mean squat during a true supply chain
crisis.
