In Brief

Thrill rides may be heartfelt

Now that it's summertime, millions of us will set out for an amusement park or a state or county fair. No one needs to be told that the some of the rides you'll find there — particularly the roller coasters — are not for the faint of heart. It turns out that they may not be good for the infirm of heart, either.
