If you have been alive for a million seconds, how many birthdays have you had?
What year was it one billion minutes ago?
How long would it take to count to a million ?
Could you run one thousand metres in one minute?
Could you eat exactly one tonne of food in a year without getting either very thin or very fat?
Could you walk as much as one hundred thousand kilometres during your lifetime?
Could one thousand drink cans fit into one cubic metre?
