My husband is 77 and had a serious accident in May. He does not drive any longer. BUT today I saw he had the CHAINSAW out. He has no upper body strength and he has tremors. I hid the thing and I need to suggest he not use it. What is the best way to approach that? I've already done it once and he said ok, now he either forgot or doesn't care. It is SO obvious chainsaws are not a good idea for him. Thank you.
