G8 summit is discussing 1 aid, 2 debt and 3 fairer trading systems. Meanwhile, 4 of Africa's former leaders are to discuss development issues although many of them have already been putting their skills to good use. African presidents used to be 5 for only leaving State House feet first. Some were 6 while others clung on grimly to power. Ex-presidents used to be rare as hen's 7. But Nigeria was an exception because the leaders had all been to 8 college together. Besides, President Nyerere of Tanzania went into voluntary 9. But under it all lay a serious issue—how to find a 10 afterwards and how to live in 11 with the successor. Some simply go back and pick up the 12 of their old lives. For instance, Amos Sawyer returned to 13 life, Albert Zafy of Madagascar is once again a 14, and Sam Nujoma is studying 15 at university in Namibia ex-presidents can also make very good 16 while others have campaigned on 17. For example, Jerry Rawlings is a much younger 18 who plays on these social 19 for deliberate effect, as a UN representative on sexually 20 diseases.
