      Wow I had to look this one up quickly as I had no idea but its around 3 billion! Although this varies drastically from person to person.

      Also, you have 2 copies of your DNA- so in reality, around 6 billion! To put 3 billion into context- if you read one letter of your DNA a second until you read your whole DNA sequence, it would take you like 90 years to complete!
