I must seem like an ostrich who forever burries its head in the relativistic sands in order not to face the evil quanta.

From the standpoint of daily life, however, there is one thing we do know: that we are here for the sake of each other - above all for those upon whose smile and well-being our own happiness depends, and also for the countless unknown souls with whose fate we are connected by a bond of sympathy.
