I agree, even my dad had a try and he's in his mid-forties (tho he needed 110kg springs, lol) he didnt carry it on, because he's not the type and has too many other expensive hobbies, but you never know until you try
btw - you may want to check out sum of the posts on here for it, such as improvements, and the ones about going up in spring sizes (im 67kg and still bottoming out 90kg springs)
as for fun - there's no better bocking, and if you decide against it we will all be very dissapointed
