I'm 71, been shooting bows most my life. Best advice is as most above. Go to a shop and shop! Find one that fits. If it doesn't fit you, you will never shoot it accurately. Don't be macho and think you need to shoot an 80lb bow to kill a deer. A 50 or 60 lb bow will kill them just as dead. Trying to draw a heavy poundage bow, in a tree stand in cold azz weather can be tough. I have shot about every kind of rest made, the Whisker Biscuit IMO for a hunting bow is one of the best. They are very easy to tune and hold your arrow securely on the bow. Another thing, you don't need to spend your kids college savings on a hunting bow either. Bow prices are crazy high these days. Just get a decent bow, with a warranty, a good sight, I like a 5 pin but a 3 pin will work as well. Get some good arrows, and practice! Lots of practice.
FYI-Deer season is winding down. There will soon be a lot of bows hitting the pawn shops. I've seen some pretty good deals on used bows there and lots of time when people sell them, they sell everything. It can save a bunch of money not having to piece everything together.
