Time Dilation = Time Travel? – I don’t think so.

I don’t understand why it’s claimed that time dilation would equate to a form of time travel. Time dilation would cause an aging rate differential but that can be achieved without time dilation. A person that ages slower or lives longer than another doesn’t time travel in to the others future. In the “Twins Paradox” the “travelling” twin returns to the “home” twins present time, not future time. That the “travelling” twin is younger or that the other twin may have died of old age doesn’t equate to a form of time travel. Essentially time dilation would have merely “preserved” the travelling twin in a similar way that chilling or freezing preserves food.
