is it ageing or aging?

[gemmiegoatlegs]

my spellchecker likes both

with the e

Funnily enough I think they have discrete [note apt use of frequently misused word, just for the delectation of we pedants] meanings, & one ("aging") is intransitive, & means becoming older, & the other ("ageing") is transitive & means what wearing red latex leggings does for your given matron.

Aging it is then. Thanks!
