Transhumanism criteria

Kyle Munkittrick's criteria for transhumanism:

2. Our social understanding of aging loses the "virtue of necessity" aspect and society begins to treat aging as a disease. Concepts like "aging well" and "golden years" would be as counter-intuitive as describing someone with cancer or MS as "diseasing well." I have no idea what the consequences would be socially, but you can bet things like "mid-life crises" and "adult learning" would take on entirely new meanings or become meaningless. When we have a generation of people expected to live to 150, that'll be a good sign this is on the way to happening.

As a freelance writer, I've always worked under the notion that without deadlines, nothing would be accomplished. I wonder if this sort of mentality would begin to seep into daily life if average life spans pushed 150 years? How would this effect productivity and the urgency of human thought and emotion?
