With some cigars when paired with the tolerance of the smoker, you can feel the effects of the increased nicotine levels. In some people this will result in lightheadedness and others will feel different levels of nausea up to including getting sick. But the same cigar will not have the same affect on all people.
It is also a mistake to pair aging potential with strength. Certainly most strong cigars will mellow with a few months rest in a humidor, but to most this is not aging. Aging is a process that takes many years if not decades. This is not a process that is usually practiced with non-Cuban cigars.
Some smokers prefer fresh cigars and others like to let them rest for a few weeks or months to take the edge off. Its merely a matter of preference and has little to do with the quality or strength of the tobacco.
