Is 70 the age to stop towing

I think 70 is the new 60 or however that goes. With everything we have in todays world for food, medicine and exersize more people are more fit than before. We live in a more health conscience society today. I'm 64 and no way feel that I can't keep doing what I do for 10 more years. It's all about staying active and eating right. As long as your mind is sharp then there's no reason someone can't keep RV'ing well into their 70's. You might not be as fast at everything but at that age time doesn't matter. What else do you have to do? :)
