Admire his hardworking attitude, don't patronize him as if he's a delicate flower who will wilt if the wind blows the wrong way. Yes, there have been deaths from overworking. The vast majority of the world's population that overworks themselves do not die. He's more likely to die from his caffeine and cigarette habit than overworking, and this is from someone who has done both. I've worked retail, I've worked in a hospital, and honestly, getting off at 10pm after a 12 hour shift and having to come back at 5am when you live an hour away doesn't leave time for sleep a lot of times. Many of us have pulled 16+ hour shifts, many of us have worked two or three days in a row with no sleep, and many of us have worked for around 30 days straight with maybe a day or two off after that stretch. Yet we're all still here.

Be grateful he's working on the game, he obviously loves his work and he has his eye on making a name for himself since he took on this monumental task. Showing appreciation to a man you don't know, but admire the hardworking nature of is considered appropriate. Buying gifts for a man you do not know is typically considered a bit odd.

I'm sure this will be taken the wrong way completely, just like everyone else stating that there are plenty of other people, who most people seem oblivious to since it's outside of their personal life, who -should- be looked at with much greater admiration than Yoshi. He should be recognized for his hard work, but anything else outside of treating him like you would any other person working just as hard comes off as very fake, or very naive.
