Invitation to a lifelong learning experience

Resumen

We live in an ever-changing world, in which knowledge experiences immense, exponentially increasing momentum. What is common knowledge today, might not have been known yesterday, and could be of no use tomorrow. Knowledge´s average life could be defi ned as the time between the acquisition of knowledge and the time when at least half of it becomes obsolete. Average life of professional expertise would then be the time elapsing from the moment a subject completes professional training up to the time when the aforementioned training becomes only half as competent as when it started. Actually, during his first professional stage, the subject is inexperienced, and experience enhances any skill.
