1. I don't want to create an extra variable.  It is a simple loop to 
count down 35 times in a short program.

2. I want 35.times because it says it is 35 times, very clearly. 
35.downto(1)  you will need to think a little how many times it is.  My 
purpose is to do it 35 times, so 35.times is best, but I need the count 
down.  Something like

35.times.countdown do |i|
  print i, " "
  # do something
end
