You can teleport. You can go wherever you want, and it appears instantaneous, but in fact time elapses as if you had traveled via mundane means, walking, driving, flying etc. Going from your bedroom to the kitchen will take a few seconds, going to work might take half an hour, and going to the other side of the globe might take a day.

The big cost: While you're teleporting, you age twice as fast as normal. You also expend resources double what you'd do using regular means of travel. You might arrive hungry, and your bank account is mysteriously drained of gas/ticket money. Once you activate the ability, you can't abort, or stop for food/drink. If you're not planning well, you might arrive dead of thirst.

Obviously, you can use the power to get into places you couldn't normally access, e.g. you can jump into a bank vault and get rich. And as long as you're careful and eat/drink plenty before you go, everything should be fine...

You lose the "travel experience" but perhaps you're fine with that. Are the other costs/risks too high? Do you think you could keep from overusing the ability, or would it be an acceptable drawback that your lifespan would be cut short?

Edit: Clarification: During transportation, you are frozen in limbo. You don't perceive this; it seems to you that one second, you're in one place, the next, in another. If you see on your alarm clock that you've overslept and that you have five minutes until an important meeting, and think "I must put on some clothes and jump to work", everyone at the meeting will be angry with you for being late.
