Your sister is 67 years old, as when you were 6 she was 3 years younger than you.

How old was she when I was 2?

To find out how old your sister was when you were 2 years old, you can use the same approach as before.

If your sister was half your age when you were 6 years old, that means she was 6 / 2 = 3 years old at that time.

The age difference between you and your sister remains constant, which is 70 - 2 = 68 years.

Therefore, your sister's age when you were 2 years old can be calculated by subtracting 68 from her age now:

67 - 68 = -1

This means that your sister was not yet born when you were 2 years old.
