Dear Lifehacker, I have a question about the rights of bottle shop assistants to check IDs. I was at a bottle store a few days ago with a friend buying two bottles of beer. The checkout assistant asked for my ID which was fine and even a bit flattering (I'm almost 30). But then she asked my friend for her ID too.

Dear Lifehacker, Lots of people are chronically late, and one big reason is the habit of always trying to do 'one more thing' before heading to an appointment. I suffer from this, and I've asked enough people to know that I'm not alone. Such people plan their day carefully, they know what time they have to leave, but they think 'I'll just do this one more thing before I go'. And that turns into another, then another, all small and probably non-urgent tasks that should only take up a few seconds but end up taking minutes, and then they end up late! Is there any way to deal with this? Thanks, One More Thing

Dear Lifehacker, I consider myself a pretty organised person. The rest of my family? Not so much. It's not that we're totally out of control or anything, but with three kids, there are lots of activities, messes abound, and schoolwork is always a hassle. What can I do to get us all more organised and in sync with each other?

Dear Lifehacker, Recently I have been confronted with a staggering number of various spiders. I am not bothered by the majority of them, but red backs, funnel webs and other poisonous specimens are a little unnerving. What's the best thing to repel or kill them, other than straight poison from the hardware store or a large boot?

Dear Lifehacker, I have been working on a comic series for a while now, using a free software with a limited sprite library. I am now getting to the point where I want to have it illustrated so I can sell copies at conventions and the like. My question is: how much I should pay the illustrator?

Dear Lifehacker, I'm thinking of moving on from my current job, but there's a problem. I have some health issues that require a weekly appointment and I currently have my appointment on a Friday afternoon. My current manager has rearranged my work hours slightly so that I can attend this appointment. My question is: if I get an interview for a new job, should I tell them about this at the interview? If so, how do I go about it?

Hi Lifehacker, My fiancé and her parents are looking to sell their beauty salon so they can open a coffee shop. To keep an income stream, they want to continue working in beauty from home with existing customers. Is this possible or are they subject to some form of goodwill when it comes to the clientele of the current business?

Dear Lifehacker, I've heard that I should be "mixing it up" and changing up my workouts at the gym. My friend, who's a bodybuilder, told me that this is called "muscle confusion" and will force them to grow. I only know a few exercises at the gym so changing seems even more difficult. What do I do?

Dear Lifehacker, How can I get rid of the dark circles under my eyes? I sleep and drink lots of water and it lightens but never goes away completely. My employer has even assumed I'm a heavy-drinking night owl! Any advice?

Dear Lifehacker, Everyone is saying artificial sweeteners like aspartame are bad for you, and now Diet Pepsi is removing it. Should I worry about how much diet soft drink I've been drinking? What health hazard have I been exposing myself to all these years? And should I worry about the new sweetener that's replacing it?

Dear Lifehacker, I know you've offered tips on beating the heat in the past but this week takes things to another level: the temperatures are so high, especially in Sydney, you can fry an egg on the bonnet of your car in the early morning already. How can I cope with this stupidly hot weather?

Dear Lifehacker, I admit it, I sometimes watch those dubious "current affairs" shows, and it has me wondering: can you request a TV crew to stop filming, and are they breaking the law if they don't stop? And what if a cop asks me to stop videoing them?

Dear Lifehacker, I have recently moved interstate and started a new job. What's your best tip for getting myself known to the people that matter while still maintaining a good relationship with my peers and staff? I don't want to be a brown nose but I have come from a well-respected position - I knew the movers-and-shakers both within my organisation and without and I want to get back to that point as quickly as possible.

Dear Lifehacker, I get extremely bored while working out. When I go for a run, I'm just counting down the minutes until I get home. When I exercise, I'm too distracted. Listening to music doesn't help. What can I do to make working out more entertaining so I won't give up and do something more interesting to my brain?

Dear Lifehacker, In the past, I've assumed most doctors are charlatans, and only visited them in matter of dire emergency (needing a sick note for work, week-long flu, etc.). I am now reaching a point in my life where my body and mind are getting older and I am reconsidering past decisions.

Dear Lifehacker, I've recently relocated to London for a year or two and am looking to start work. Most of my applications have been via recruiters who have responded with a range of roles. I'm interviewing for a couple of jobs this week but one is about 90 minutes away in another city and the other sounds like good work but the organisation might not be the right cultural fit for me.

Dear Lifehacker, After going through my third pair of earphones for my mobile in recent times, I was wondering if there is a "preferred" way to keep the phone in your pocket? Do you have the lead facing upwards from the outside of the pocket, or down towards the groin? I'm sick of my earphones not lasting a year before the connection becomes sketchy.

Dear Lifehacker, Is it okay to have cameras installed in home swimming pools? I want to rig one up for a variety of purposes, but don't want to get fined for doing so! Any advice?

Dear Lifehacker, The air conditioning on my car recently broke down, and the quote for replacing it is around $3000. So I am considering trading in my broken car and getting a new one. The car still drives fine and the A/C button still lights up, but no cold air comes out. If I am trading in my car, do I have to tell the dealer about the broken air conditioner? Is it a case of "only tell them if they ask" or do I have to tell them from the start? Thanks, Cold Comfort
