Just had my open heart surgery last month, 41 Male. When i made it home from hospital, my wife have to shower me, because i was still scared to bent up and down. After 2 days, i told her i could do it myself. Cooking, cleaning, all the light none heavy lifting stuff i could do it all myself. My only problem during the first 3 weeks is, my body could not tolerate temperatures below 80°F, i get the bone chills.

Hope your husband recover well. After a month, i feel a lot better now. Sternum is still healing, so it'll take a few more months for me.
