Oh, yeah, that's not where I'd like it to be at all. I follow the Starting Strength plan, and so when it's been a while (more than a couple weeks) since I've lifted, I do a total reset where I start back at the bar and add weight 10 lbs. at a time until my form starts to change noticeably. For whatever reason this last time my squat and bench reset to about the same level. There's certainly more muscle groups in the squat, so I think it's just a bit trickier. Today was a 135 lb. squat, and it felt good, so I should have it well in front of my bench in a couple weeks. It's just hard when you get sick or go on vacation to really keep up your weightlifting.
What's your age? Unless your relatively advanced in age you shouldn't need to reset to a 45lb bar each time you take time off. While you shouldn't be starting exactly where you left off you should be starting heavier than a bar if you want to be serious about lifting. Or are you doing sets of 20-25?
Ideally you should be able to do body weight on legs without much difficulty, if you can't you should be working towards that. Some people do a lot more than body weight.
Legs provide foundation for other lifting as well.
Stay consistent if you're looking for fitness and health gains. Which means be consistent in your days on and off of the gym, sleep, and eating habits. And change your routine from time to time in the gym in order to avoid plateaus. If you're always doing squats for instance try leg press/leg extensions, hamstring curls.
