Another question - you mentioned that even as an eye surgeon accustomed to working with fine instruments, you found the lactate meter challenging to use. I have zero experience with medical tools, so the process feels a bit intimidating, especially after hearing a medical professional experiencing challenges. Do you have any advice on how to approach it as a complete medical device newbie? Would it make sense to practice a few times while standing still before trying it on the bike? Lastly, do you have to dispose medical equipment like this a certain way? Appreciate your thoughts!
