if you have given a chance to go back to the past I a year of 1930's to 1960. What would you like to invent? What is the function? And how useful is that for the future?
i think I'll invent a mobile phone so the lovers and family members will be able to contact eachother without hesitation or they'll not get tired of walking to their homes or get tired of sending letters.
