If I could go back in time, I would...

If I could go back in time and change a turn of events, I would stop the sinking of the titanic. First I would go back and show them that they do not have enough life boats on the boat before they send it off to sea. Next I would warn the captain of the dangers of running into icebergs in the middle of the ocean. Thirdly I would warn the passengers of the danger of such a big ship and teach them the proper way to leave a sinking ship. And lastly I would board the ship and make sure nobody makes any of the mistakes I warned them of.
