You have had this long arm purchase as part of your plan when you downsize in your move. My guess is you have thought it out, maybe tried using a LA, and envision it enriching your life. I say if you are familiar with the strength and stamina it takes and are okay with it, if you have the money and space, then I would encourage fulfilling the plan you and your husband have thought out. Your friends may simply be projecting their personalities, habits, budgets, and health onto you. It’s not their decision. Would your buying it impact them? Maybe they are jealous that you have a rewarding hobby, a supportive mate, better health, more money, etc. All that really matters is yours and your husband’s agreement because it is a big purchase and takes up a lot of room. But it sounds like you two have already thought of all that. I personally would rent time on one and see if I could get the hang of it. But if I enjoyed it and hubby was in favor, I’d dismiss everyone else’s input. .
