The amount of gifts you would receive would be 78 gift's.
Explanation:
The way that I got 78 was by I added all the 12 number's which would be <em>12+11+10+9+8+7+6+5+4+3+2+1=78 I know they are those number's because each time there was a gift added and it would not be 12 because those where the amount of day's the gift's were gifted.</em>
Well you can’t live without food and water because water hydrates you and well food keeps you not from starving cause it could possibly kill you I’m pretty sure so yea
