KEEPING WARM 
tainers for these products warn users 
about the need for adequate ventilation, 
but that may be hard to provide in 
winter. Because many of these solvents 
are toxic and carcinogenic, they repre- 
sent some degree of health hazard even 
j though we do not yet know how serious 
| occasional exposure to them may be. 
Gaseous and particulate pollutants 
from gas stoves, cigarette smoke, 
cooking food, and other sources 
can accumulate in houses where 
caulking and weather-stripping 
prevent the leakage of indoor air. 
Exposure to the fumes of various sol- 
vents is infrequent and the incipient 
pollution can be recognized by the 
smell; the problem presented by radon 
gas in the home, however, cannot be so 
easily dismissed. Radon, which is re- 
leased by radioactive minerals, can en- 
ter private homes in very small quanti- 
ties from rock basements and masonry 
materials used in construction. Odorless 
and colorless, radon cannot be detected 
by the occupants. The long-term health 
effects of exposure to trace quantities of 
radon gas are not known with certainty; 
nevertheless, there is reason to believe 
that exposure to this radioactive gas 
increases the risk of cancers. Most at 
risk are occupants of poorly ventilated 
homes with exposed rock or masonry

Jarless Total Body 
Cardiovascular Exerciser 
Duplicates X-C Skiing for the 
Best Motion in Fitness 
Highly Effective and Pleasant To Use

often cited as the most perfect form of C-V 
exercise Its smooth, fluid total body motion

heart rates seem easier to attain than when 
jogging or cycling NordicTrack closely simu- 
lates the same pleasant motion and provides

Better Than Running 
NordicTrack gives you a more complete work 
out — conditions both upper body and lower 
body muscies at the same time Fluid jarless 
motion will not cause joint or back pains as 
jogging or running often does 
Better Than Exercise Bikes 
NordicTracks stand-up skiing motion more un- 
iformly exercises large leg muscles and also 
adds important upper body exercise Higher 
pulse rates, necessary for building fitness 
seem easier to attain because the work is 
shared by more muscle mass The Nordic- 
Track also keeps more muscles in tone 
Even Better Than Swimming 
NordicTrack more effectively exercises the 
largest muscles in the body, those located in 
the legs and buttocks These muscles mam 
function is to lift and propel the body in the 
standing position. When swimming, the water 
supports the body thus preventing these mus- 
cles from being exercised as effectively as 
when they support the body in a standing 
position.
