If you had a time machine...
If you had a time machine and could go back to change one thing, what would it be?
1 You can do any thing you wanted provided you took no more than 30 days to complete the task. You are able to teleport once a day between locations within that same time period (for long distance traveling purposes)
2 You will be given a very small computer which fits in your ear. This computer will translate languages for you and when you speak it will allow others to think you are speaking their language (making them think your lips are moving in sync). This will fix the issue of communication
3 You can also use this computer to access information as needed concerning the time period you are located.
4 You will be unaffected by disease or viruses and you will not infect others
5 You are not limited to various technological possibilities. Meaning that you could do almost any thing with technology.
