Normally I don't bother too much about age, feeling old, mortality etc etc, but the whole "celebration" of this milestone (we have a party & BBQ planned) seems to make me think about it now. The poem describes exactly the sort of feelings I would prefer to have about ageing & mortality.
The poem is by Roger McGough...... He has some other wonderful & droll poems as well. If you have not read any of his, then take the opportunity to do so if you can.
