That's not logical either, because if ALL players were to be sold by that age, and by your assumption, all clubs shouldn't buy older players.. given that players are human and their ages increase, this leads to a contradiction.
Selling an over 29 or 30 year old player implies the purchase of that player by another club.
Therefore, the proposition of "all players should be sold at the age of 29, 30 at most" is impossible and thus not logical.
My vacation has lasted a bit too long I think. Don't worry, classes start next week.
