I've always been interested in time travel. Read a whole lot of time travel romances in my younger years. But the scientific half of my brain kept trying to ruin it by asking stupid questions, like " what if you ended up in Pompeii on the day before the volcano erupted? Would you warn them, grab a boat and get the hell outta dodge or what?" Or what happens if you're able to stay in the past, wouldn't that negate you being born so you wouldn't be around to go back to the past? Ouch, brain hurts. Gotta get off that hamster wheel. Anyway, I'd rather be like Dr Who (David T or Matt S please) where I can pick where I'm going and prepare. I loved to have a Tardis.... I'd never be at home. Thanks for this brief piece (and now I'm stuck on that wheel again).
