I am 75 yrs. old but love my flower beds. Is there permanent damage from over working my body from digging etc.? I get to the point where I can hardly move but go back at it the next day. It is my one vice (you might call it ) because I can`t seem to stop at this time of the year.Digging + planting new clematis vines etc. It is hard ,heavy work.Am I causing long term problems for myself?
