I have about 80% in index funds and Roth IRA that I never plan on touching until way later. About 15% in Ally savings account at 4.5%, and the rest on hand. The nice thing about Ally is that you get the nice interest rate, and you can pull from that pretty easily.
I just finished Pluto again after about 10 years. It is also great. Reading Billy Bat now and that reminds me a little of 20th Century Boys.
