What happened to the Fibonacci sequence?

I'm sure you've seen some of these numbers before:

1 3 8 13 21 30 36 45 54 63

Whats the next number in the sequence? And what have I done to the Fibonacci sequence?

Answer

every number is the sum of letters (without spaces) of all the previous numbers.

3 = one (3 letters)
8 = three (5) + one (3)
13 = Eight (5) + three (5) + one (3)
21 = Thirteen (8) + Eight (5) + three (5) + one (3)
30 = twentyOne (9) + 21
36 = Thirty (6) + 30
and so on....

It's still a Fibonacci series of count of letters of n-1th value & number of n-2th value
