Mate , It warms the cockles of my heart to read this post . I am a firm believer of " if you think old , you get old " ! best way in the world of getting and / or keeping fit . I have remained 9 for the last 43 years and have no intention of getting any older , despite what my body says . Just bear in mind that intentions often outweigh abilities as we get older , so don't beat yourself up when you find it's all far harder than you remember ! I have a friend who at 75 years old is still regularly winning Enduros in the veterans class , and he never rode a dirt bike until well into his 60s. One peice of advice tho , get yourself good off road riding personal injury insurance . Worth their weight in gold ! Here's my baby ,
