Pass this along to your senior friends. For those getting
along in years, here is a little secret for building arm
and shoulder muscles. Three days a week works well. Begin
by standing outside behind the house, and with a 5-LB.
potato sack in each hand extend your arms straight out
to your sides and hold them there as long as you can.
After a few weeks, move up to 10-LB. potato sacks and
then 50-LB potato  sacks, and finally get to where you
can lift a 100 lb. potato sack in each  hand and hold your
arms straight for more than a full minute. Next start
putting a few potatoes in the sacks, but be careful not
to overdo it.
