Let me caution you that William Jackson Black Jersey , of course, no one knows what will happen next week, much less in 2035. If we add the uncertainty of estimating four centuries worth of progress, clearly we are in the land of make-believe. But make-believe can be fun (and instructive too)! Let's take a look. If longevity were to improve by half a percent a year for 400 years, someone with a life expectancy now of 75 years could live to be over 250! While some scientists cite 180 years as the outside limit on the potential life span, who knows what might be learned in the future? Perhaps people will grow their own new stem cells for cloned body parts that will be replaced every 50 to 75 years. Let's assume a low-ball case. Life expectancy for 60-year-olds grew by about 10 percent in the United States during the time from 1900 to 2000. If that trend were to continue for another four centuries, 60-year-olds would have average life expectancies of 120 years of age! Sixty would become the new forty. Many people will see the possibility of being aged and infirm for the bulk of one's much longer life. But that's probably not what will happen. Huge advances are being made in replacing the parts of our bodies that wear out the fastest, like knees Paul Dawson Jersey , hips, and spinal discs. Organ replacements are becoming increasingly common. We also know a lot more about rehabilitation after an injury or disease. Increasingly, those who replace body parts will find themselves functioning better than before rather than less well. With weight and exercise training, some 90-year-olds now report being more agile and active than when they were 50. As for marriage, perhaps people who realize that a life commitment to a spouse could be for more than 100 years will make the effort to learn better how to build and nurture their relationships. Appreciating that those years when children will dominate a marriage will be relatively few over the length of the marriage may also improve both spouses' interest in having a great relationship with one another. In addition, average family sizes keep getting smaller. Perhaps tomorrow's norm will be to have one child rather than two. That would certainly provide much more room for spouses to have primary relationships with one another. People who have many marriages following divorces often try to disguise that fact. Imagine what it would be like to have had fifteen failed marriages over a much longer life. Perhaps the unattractiveness of going through so many unpleasant endings to relationships will encourage more interest in better marriages. Families are an area where that 120 year life span will make the most difference. If marriage and child-bearing occur at young ages, someone who has 30 descendants at 80 could have 62 descendants at age 100 . . . and 126 at 120! Even those who marry and give birth at more advanced ages could have 62 descendants at 120. This size in the descendant population may also influence marriage length.
