 # tamagotchi
 
 ## Todo
-* make the aging work parallel the main programme
 * adding a function to decrease the health
 
 ## Possible things to add
 Some interesting things I could add to the
 tamagotchi programme which shouldn't be too hard:
 
-* ~~create a loop~~
-* ~~give it happiness~~
-* ~~give it points for hungriness~~
-* ~~add the guessing game and increase the happiness by one point when you finished the game~~
-* ~~create a list with things you can do~~
-* ~~pet it to increase happiness~~
 * poke it to make it speak, pokes let it loose a happiness point
-* ~~add max values depending on the status~~
 * sleeping with all values with over 50% full heals the pet if it has lost health
 * add pooping and cleaning function
 * let it get sick if it's health is low, by random chance or if there's too much poop
-* ~~let it age~~
 * decrease the hunger value after x seconds
 * add sleep function, you have to switch the lights off otherwise it will have nightmare and loose one health point.
 * add the possibility to get sick. Maybe compare two random numbers.
 * add a function to restart the game or exit it after the pet died.
 * add a function let the user exit the game
 * safe the stats in a text file
+* make a seperate function for each age because it makes the aging
+funciton more readable
+* add a function which lets the tamagotchi age (one week as a youngling, three weeks as an adult and two weeks as an elderly)
 
 ## 30.6.2015
 Time function has to be implemented otherwise the decrease.* functions
