Some thoughts

What is procrastination? According to Wikipedia, "in psychology, procrastination refers to the act of replacing high-priority actions with tasks of low-priority, and thus putting off important tasks to a later time." Since this is a spontaneous act of many civil human being, procrastination must be benefitial, wouldn't it? Many would say it allows us to take a breath of fresh air when we are working our s-off, some may add that one cannot appreciate the nature without taking a "break".

No, procrastination brings worry, as punishment will follow if high-priority actions are delayed; it spoils our lives, because we could not fully relax before the jobs are being done.

To live a successful life, one must carefully prioritize his tasks and eliminate those that are at the bottom of the list. 

In a word, if you are tired, go take a nap.

"Stem cells are presumed to survive various stresses, since they are recruited to areas of tissue damage and regeneration, where inflammatory cytokines and cytotoxic cells may result in severe cell injury. We explored the ability of mesoangioblasts to respond to different cell stresses such as heat, heavy metals and osmotic stress, by analyzing heat shock protein (HSP)70 synthesis as a stress indicator. We found that the A6 mesoangioblast stem cells constitutively synthesize HSP70 in a heat shock transcription factor (HSF)-independent way. However, A6 respond to heat shock and cadmium treatment by synthesizing HSP70 over the constitutive expression and this synthesis is HSF1 dependent. The exposure of A6 to copper or to a hypertonic medium does neither induce HSP70 synthesis nor activation of HSF1, while a constitutive binding of constitutive heat shock element binding factor was found...For hypertonic stress, cells were grown in a 0.7 osM medium for 45 min, or in a 0.4 osM medium for 2 or 24 h (the desired osmolarity of the medium was reached by adding NaCl)." (Nature).

Guess the cells are just fine when cultured in 2.3X PBS solution.
