# Print Sam's full name
# Print Richard's first favorite food
# Print Adam's second favorite food
# Print Helen's third favorite food

# Create an array called people that contains all of the hashes above
# Using that hash, repeat the following:
# => Print Richard's first favorite food
# => Print Adam's second favorite food
# => Print Helen's third favorite food

# Add Faizaan to our people array:
# => first name: Faizaan
# => last name: Shamsi
# => favorite foods: mango chutney, bad chinese food, Soylent

# Print each person's name and how many favorite foods they have, like so:
# "Adam Sheehan has 2 favorite foods."

# Add people's ages to their hash:
# => Adam is 28
# => Sam, Faizaan, and Eric are 24
# => Helen is 27

# Say it's a year later -- increment everyone's age by 1

# For each person, print the following:
# => If they are under 25:  "Sam is a spring chicken!"
# => If they are over 25: "Helen is over the hill!"
