Been there, done that. After about 35, I figured that I had been practicing being miserable hunting for a while, and was quite good at it. Started building blinds that were more comfortable. Last lease, had 4 blinds, 4X6, so 2 people could hunt. Each had a heater and porta-loo in it. 5 gallon bucket with a plastic toilet seat on it. Bucket lined with a plastic bag.. (Extras under it) Still have 1 of them. Saved my wife b4 we got the bedside potty for when she has a gout attack. Don't know if I will be able to hunt anymore because of age and health issues. But, my mindset will be the same. Hunting is supposed to be fun, not suffering. All I can say.
