Maybe this is different since I'm coming from non-US point of view so health care is quite different. To me it's obvious that employer's insurance covers implanting, removal, and any issues that it might cause.
The employer might no longer exist (IMO, the probability that a company that does these kinds of experiments goes bankrupt is far from negligible), deny responsibility ("you should have let us take it out when you left the company"), or not pay for all costs (say, you moved state; will they pay travel costs to their appointed expert? Pay for time lost?)
your country of origin shouldn't matter. I'm pretty sure he/she was concerned about health related medical risks, and just because the insurance 'covers' it, provides little solace
What's the worst thing that can happen? It gets infected and needs to be removed and I have to take up to few months of paid sick leave?
Maybe I'm missing something, but all in all this is convenience vs pain value comparison. Does the pain the implant might inflict outweigh the possible benefits.
I bet there is something I'm not considering or I'm misunderstanding something. To me this is pretty straight forward for now.
If it is my time to die then I will die. I don't think we should steer away from something because it is not 100% safe. Like I drive my car each day which is by no means 100% safe.
its a matter of trade-offs and choice. to me, a .000001 chance of a complication is not worth it vs 'just carry a card in your wallet'.
driving a car has many risks, and if I could opt for a card in my wallet as an alternative I certainly would.
I am curious to how old are you roughly? it seems like you are stating you can get a medical complication, take a few weeks sick leave and return to your life, which makes me think you are <25
It really depends what you mean by "medical complication". If we are assuming that we are getting the implant at hospital by a qualified physician risks are already at minimum.
Most likely "complications" would be body rejecting the implant or the wound getting infected. I've had foreign objects in my body (not by choice), they were removed because the wound got infected. I was monitoring the wound, once I thought it didn't look/feel normal I went to clinic and got it checked. Over all I wasn't out of commission for even full four weeks.
You can not control everything. Obviously everyone would prefer to be healthy to being sick or crippled, but getting implant like this is hardly the most dangerous thing people do.
Since I'm not American I can't obviously speak for you. For me money wouldn't be an issue since it would be obvious in this case that the company would bare all the medical costs involved caused by the implant.
