Lastly , I have a long list of things I want to experience in this lifetime and I chase those goals whenever I get the chance . For example ... I wanted to save someone 's life , so I donated a kidney ( which was why I was in the hospital earlier this year ) . Little Soul announced that her university is somewhat near a town that 's famous for adventure tourism like bungee jumping , skydiving , and jet boating , so we ' ve decided to do all that when I visit . She also wants to try to teach me to snowboard , which makes me nervous .
