My preference is, pretty darned close. When you get there, you'll feel why. I checked the converter, 36.74 C is 98.1 F. I will tell you that even when my temp is no lower than 98.4 F (36.89 C), I still feel like I'm moving through water all day. Plus, my muscles ache. Now that my temps have increased, I really enjoy 98.6 F (37 C) or even 98.7 F (37.06 C). When I get there each morning, my brain turns on just like a light bulb, and, I get creative. I love it. And I wish it for everybody.
