Apart from the unconditional love, there is also the fact that your parents gave birth to you and natured you all through which is a lot. You therefore naturally will want to take care of your parents in their late years, the reveres parenting. Here is how you can properly do that well.
You need to know that your parents are okay and they also need to know that their child is okay, which makes frequent contact a great place to start. We live busy lives and work hard, and it is very easy to lose track of when we last spoke to our parents through things like marking the calendar. If they are tech-savvy, video calling them will be better since that will feel like you actually visited. This is especially important if one of the parents recently passed to avoid the one alive falling into loneliness and depressions. It is important however that you remember that there is no amount of the calls that can constitute for a visit. Seeing them in person helps you see things that you would otherwise have missed.
They will need the elderly caring in the futures, which is not exactly cheap and this is another thing to plan for. You should consider everyday expenses of their potential medical care and their living costs. It may be hard to have the financed conversation with the parents but this is very important. They need to be aware of the potential financial exploitations and the abuse that they may face.
The other thing that you need to worry about is their sociability since a third of the seniors have been reported to be lonely. Meaningful social contacts that can be through seeing an old colleague or friend and volunteering will help than a great deal once in a while and when you visit, you should research, find suitable social gatherings and encourage them to go. Pets, apart from the fact that they are great companions, also gives people a sense of purpose and something to do like walk a dog and this is another thing that you should coinsure introducing into the home.
Activities that you can do with them like go to the cinema gives them something to look forward to and a chance to spend time with you. The modern technology, if you can teach them, will add a valuable dimension to their social network too. Safety features like stair and bathroom railings, bright light and accessible switches and a step stool ensure that they are safe and their home should be safe. You parent still need their independence and some little help, and you have to remember to find the right balance.
