- Physically strong and active.
- 1976, Joni Mitchell (lyrics and music), “Song for Sharon”:
- Now there are twenty-nine skaters on Wollman Rink
Circling in singles and in pairs
In this vigorous anonymity
- a vigorous scrub
- a vigorous search
- Mentally strong and active.
- Rapid of growth.
- a vigorous shrub
physically strong and active
