In a small way, my birth expanded the popularity of motorcycle racing in my county. In 1971, I bought the first real 'race bike' from a local dealer. Then some buddies bought race bikes. Then dozens of folks bought off-road bikes. Along came all terrain vehicles and every farmer in the county bought one. So, in a way, I introduced a lot of people to the fun of off road riding.
Let's be realistic here: what about all the tildes that would have gone unherded, and more importantly, who would have been on constant grammar patrol here?
Ha ha what an inventive question! Honest answer? No, not necessary.. I think the world would have done just as well without me.. But I have made many a contribution, things wouldn't have happened without me, other things would have happened that shouldn't have... and who knows what my offspring and their offspring, (if they have any) might do...
I have saved the odd beetle from drowning.. so I am sure my life, on balance is a good thing in the scheme of things :P
