A Swahili saying that goes 'ujana ni moshi' loosely translating to youthfulness, is like smoke- it dissipates quickly and before you realize it is gone. The saying is usually used to warn the young against wasting their years and to be more intentional in planning for the future.
I have spent a few days in the village, and this saying could not have been more accurate. In my short stay in the countryside, I encountered the youths of the 90s, grey and wistful.
