Two New Variations on the Twin Pseudoparadox

Two new scenarios are proposed which generalize the standard story leading to the pseudoparadox of the Einsteinian relativistic twins, thereby enabling some deeper understanding. First, the fable by Aesop 'The Hare and the Tortoise' is considered in the light of Einsteinian chronogeometry. It is then shown that the Hare, while arriving later than the Tortoise, may still be the winner of the race (or at least may consider itself to be). Second, the situation is considered where the twin initially left at home decides to catch up his brother during his travel. Can they meet so that they may celebrate a common anniversary and recover the same age?
