I have a document called 'organiser.org' which is mainly comprised of various
TODOs under various projects, and various NEXT under birthdays and hospital
appointments. These TODOs can be up to 4 levels in depth, and with one level 1
TODO as the project header. How can all of these TODOs be included in the agenda
please?

And for the birthday TODOs, how can I include the date of birth so that it shows
their age please? Like - 
,----
| *** TODO Winnie Poohs birthday - is 83
| SCHEDULED: <2014-12-02 Tue> AGE: <1930-12-02>

Thanks
Sharon.
