There is a group of senior fellows that meet for lunch on Fridays - they all ride motorcycles and at 67 I am in the youngest one in the group. Several of the riders are in their 80's......unfortunately the two fastest riders are showing their age and given up riding this year.
Some of them have several bikes in their garages, and at one meal they started talking about how they don't ride them enough and they worry about the batteries and freshness of the fuel.....the bikes need to be ridden more.
I offered a service to them - I could come over frequently and ride their bikes for them at no charge. The bikes would get "exercised" and kept it top form!
One of the orneriest fellows asked if I could do the same thing for their wives! I told him that riding motorcycles is risky - but that kind of activity is far too dangerous!
