A Grassroots Remedy
A.Most of us spend our lives seeking the natural world. To this end, we walk the dog, play golf, go fishing, sit in the garden, drink outside rather than inside the pub, have a picnic, live in the suburbs, go to the seaside, buy a weekend place in the country.

At Iowa, when my first classes began, half of my students still hadn’t arrived. When everyone finally found a seat, ringing cellphones and loud yawns (哈欠) interrupted my opening remarks.
